I've only watched part 1 so far. It was okay, but it had alot less scifi than expected and alot more ordinary detective story vibes. I'm also upset that so far the only female character is an alien! Apparantly only males can be heroes, woman are all aliens tsk tsk! The writer must be a man who hates women. This is 2017, SOME DIVERSITY PLEASE! #UpsetFeminist #FemaleWhoLikesScifi

@JulySnow2 I agree, there is certainly a lack of female characters in this story. While I wish there could be more women in the story, I don't think it's a bad thing that one of the female characters is an alien... We don't know much about the alien yet, her motives and her personality to judge that character as someone entirely displeasing. There are more female characters in Ep 2, and we do find out more about the lead female character, but yeah... I do wish they could've turned more characters into women. Anyway, this drama probably isn't for you, as it's been established that there are really more male characters and that the story is most likely gonna revolve around the twin brothers.

@Elisa Yup, and a lot of the questions from Ep 1 were made clearer through Ep 2. :D

thanks should i watch this now or wait ?

@Aden Depends...I've seen the first episode, and so far it's really good. So if you like to binge watch dramas, wait. If you're like me and don't like binge watching dramas, watch it now. 

@MrBanana I also prefer 2017 more, ugh the brother story is so good! Both of them are great actors. But the 2037 part has me intrigued. Like which brother is main guy? How did the world get like that? What are the many awaiting secrets of SmartWorld? Who is the other twin brother? So emotionally, I like 2017 more, but intellectually I like 2037 more.

CONS

• The CG isn't perfect
• BGM can get a bit too much especially in the first 2 episodes
• You might get initally turned off by the different tones in the 2 parts (Part 1 is more serious Part 2 has a little bit more comedy)
• Some people say they get confused about the story (although questions do eventually get answered every episode, so it's no biggie for me)

PROS

• Amazing casting, everyone's doing an A+ job portraying their roles
• The story - you'd be able to sense how it's been planned really well 
• How the two timelines really connect so well to each other
• Plot twist after plot twist after plot twist - this show is good at their reversals
• No dragging parts
