“If you want to protect something, then you just do it.”

i went into this film unaware that it was a sequel but i think that was for the best because i would’ve been far more disappointed with this, and i already am.

mantis tries to be a lot of things at once—a comedy movie, an action flick filled with gore, a heartfelt emotional film that focuses on its characters—and it fails at doing most of this considering its less than two hour runtime. i was excited for this because the casting was literally insane and their performances definitely carried the film, but that was the extent of this movies greatness. i absolutely loved park gyu young’s performance and i think her character was the most fleshed out, with jae-yi’s inferiority complex and struggles clearly being her driving motive and acting as the main conflict of the movie as she makes her decisions based on these emotions she’s experiencing. i also thoroughly enjoyed choi hyunwook’s performance as benjamin because he does such a good job playing these bratty and manipulative characters, similar to his character in taxi driver whom i also loved even though he was a little shit. yim si wan’s character han-ul was a very basic character who didn’t have a lot of depth but it was his acting that made him stand out when he wasn’t in an action scene. speaking of those scenes, they were enjoyable for the most part but the best one was honestly the opening scene. the final fight was also slightly memorable but mainly because of a singular shot of yim si wan’s heartfelt and anguished facial expression.

other than the points mentioned above, the rest of the movie is honestly boring. the entire movie is rushed which makes the pacing really off seeing as before i knew it an entire year had somehow passed in the span of like five minutes, there are funky shots in both the good and bad sense as some of them were fun but a lot of them looked ridiculous, and the plot tries to do a lot at once with the sort of love plot between han-ul and jae-yi, the betrayal plot, the group break up, overthrowing and recreating the killer for hire system… it’s just a mess and it’s only mildly entertaining at best.

i definitely won’t rewatch this and i wouldn’t really recommend it, but if you really want to give it a shot i’m sure you’ll at least enjoy the performances done by the really incredible actors in this.

Decent action movie that left much to be desired

I think that to some extent, my disappointment over Mantis derive from my expectations. I was very excited when I had seen that Si Wan and Park Gyu Young would be in an action movie. The plot of Mantis sounded very promising and the rest of the cast caught my interest, so it was only logical that I would be excited.

Looking back at my initial reaction, I think I should have set back my expectations.

Even from pretty early on onto the movie, I was getting some mixed signals. The film started off well but it lacked the thrill and the pacing was off, especially during the middle part. To be frank, I'm not even sure if the writers were certain about the direction of the movie. Throughout the whole time I was watching, the writing felt disjointed and messy and for the most part, my interest was low.

The direction of Mantis was not very clear. While in Kill Bok Soon the direction of the story was clear from the start, in Mantis I genuinely did not know what to expect. And I'm not saying that as a compliment. Did they want to focus on the comedy? Ha Nul's crush on Jae Yi? Hierarchy and power? It was as if they wanted to cram many things together but since the movie is not even 2 hours long, they couldn't flesh out the story properly.

I appreciate the fact that just like in Kill Bok Soon, the writers wanted to highlight the characters' relationships, particularly Jae Yi and Ha Nul's. Even though I didn't expect the movie to lean on that aspect, I didn't necessarily complain and for the most part, I found their dynamic to be quite interesting. But just like the rest of the story, it fell flat pretty quickly. I wish we had gotten more scenes from their past to add more depth in their friendship and backstory. It was clear that both cared about each other but their relationship was presented in a superficial way.

The action scenes were good and well choreographed. Jae Yi and Ha Nul's fighting scenes were exciting to watch and I liked the differences in their fighting styles. That being said, for a movie that marketed itself as an action-packed one, Mantis did not have many thrilling fighting scenes. The action aspect was not that strong to leave a strong impression and the fighting scenes, albeit serviceable, were lackluster. I was especially disappointed at how little we saw of Si Wan in action, you advertise his character as one of the top assassins and give him so few fighting scenes?

Aside from the poorly written story, the characterisation also left much to be desired. The actors did their job of course, they carried the movie on their backs but their writing didn't do a lot to make them very interesting.

Jae Yi was by far the most developed and explored character. I liked the direction of her motives and how her inferiority complex towards Ha Nul was handled. Park Gyu Young did an excellent job portraying Jae Yi's frustration and bottled up feelings through her expressions and body language, you could easily tell what Jae Yi thought and why she did what she did.

Jo Woo Jin also did a good job with his character, Dok Go who was Min Gyu's former friend. He was commanding and despite his calm exterior, you could sense how dangerous he could be. I admit that relationship and fall-out with Min Gyu mirrored very well Ha Nul and Jae Yi's relationship, I liked the parallels between them. Still, I think that in terms of writing, Min Gyu in Kill Bok Soon was more interesting to watch. Dok Go was kinda one dimensional and I didn't find myself caring a lot about him.

Choi Hyun Wook was a pleasure to watch. His character was also pretty shallow but his performance made him more than entertaining. I liked the way he carried himself, he certainly fit in Benjamin's cocky and overconfident personality and he delivered exactly what was expected from him.

Unfortunately, Ha Nul's character was one of my biggest let-downs. I had expected something entirely different and although I was willing to see the direction of his character once I realised that, the writing didn't do him much favor. I expected a ruthless assassin and I got a kinda immature professional who constantly yearned for his crush. Which is not necessarily bad. We love yearners in this house but in order for me to do so, the character himself should be written in more depth. That wasn't the case with Ha Nul. He came across as too one-dimensional for me to care about him more. His main motive was to protect Jae Yi because he loved her and had a crush on her. Okay. Anything more than that? The film didn't elaborate any further regarding his feelings. The writers (and the characters) tell us that Ha Nul likes Jae Yi and viewers have to accept it. His personality was reduced on his crush, there were some attempts to add more layers in his motives but anything else fell flat. Had it not been for Si Wan's acting, nothing would be able to save Ha Nul from this disastrous writing. For a main character, he really was pretty boring.

Additionally, even though the film tried to establish Mantis as this unbeatable assassin, whom everyone respects, the writing never left any room for him to shine and showcase his potential, until we reached the final part. I was never convinced about Mantis being one of the top assassins like I was with Gil Bok Soon, the writers certainly didn't do much justice to his reputation.

So, Mantis was an average action movie that fell flat in terms of writing. It's a pity that with such a great cast and good production the writers couldn't lock in and provide a better story. Although Kill Bok Soon also had its flaws, it was more thrilling to watch and the story and characterisation were more engaging. I would recommend Mantis to people who're looking for an action movie but do not go in with high expectations.
