The Most Moving Zombie Drama — I was so Invested
Final review:
The Last Oath won me over very early, and the finale only confirmed why I had been so invested all along. The story kept surprising me, kept widening in interesting ways, and gave its characters room to make messy, frustrating, very human choices. There were absolutely moments when I wanted to shake Lin Zai and tell him to just have a conversation, but even then I understood his motivations, even when his execution was questionable. The finale gave me the emotional payoff I wanted, including a genuinely moving goodbye that had me in tears, and yes — this does have a happy ending. For a drama I almost avoided because I am not a zombie/apocalypse person, this became one of the strongest and most memorable surprises of my year.
Below are my ongoing reviews as I watched the drama while it aired.
Review after episode 17:
I never thought I’d love a zombie show!
The biggest change since Episode 14 is that the romance has gotten much messier — in a good way.
A Lie and Lin Zai are not just “together now.” Lin Zai is actively wrestling with what it means to love someone who has essentially been shaped into a human weapon, while A Lie is finally admitting how deeply attached he has become. Their relationship is still tender, but now it also hurts.
One of my favorite things is how differently A Lie behaves in public versus in private. Around everyone else, he is almost unreadable. Alone with Lin Zai, he smiles, teases, touches him constantly, and turns into a completely different person. That contrast makes the intimacy feel especially personal.
The second couple has also become much more interesting than I expected, especially with the half-zombie situation, which has raised several ethical questions and one extremely important practical one: what exactly is the safety protocol for kissing half-zombies? He Yao was awfully brave with Sheng Chang Huan. Protection is important!
The story is also widening beyond simple survival. We now have research into reversing infection, questions about immunity, secrecy, sacrifice, and people making increasingly questionable decisions because they are desperate to save someone they love.
And Episode 17 hurt. A Lie’s quiet heartbreak was brutal. The scene worked because he is usually so contained, so watching him finally say what he feels and then break down so quietly hit hard.
Review after episode 14:
I am not a zombie/apocalypse person at all, so I honestly did not expect The Last Oath to work for me this well. The first episode was the hardest because there is a fair amount of zombie action, but if you are on the fence because you are worried this is just going to be people running from zombies for 24 episodes, it absolutely is not.
The real strength of the drama is A Lie and Lin Zai. Their relationship develops through mistrust, danger, caretaking, forced proximity, attraction, and gradually deepening attachment, and the progression feels very natural. Their chemistry is excellent, but more importantly, the emotional development supports the romance. When the intimacy comes, it feels earned rather than inserted just because this is a BL.
The acting has also impressed me a lot. Both leads are very good, especially in quieter scenes where so much is communicated through body language and expression. The cast is relatively small, which keeps the drama focused, but the story has started opening up in interesting ways beyond just the two leads and the immediate zombie threat.
The production is much better than I expected too. The action is effective, the locations work well for the post-apocalyptic setting, and the drama manages to create tension without needing constant large-scale spectacle. The vocal soundtrack is especially beautiful. Several of the songs are memorable enough that I have actively wanted to find them after the episodes ended.
What I like most is that the zombies are the setting and the danger, but they are not the entire plot. The story is really about trust, survival, loyalty, attachment, betrayal, and the choices people make when the normal rules of life have disappeared.
At 14 episodes in, this has become one of the biggest surprises of my current watch list. It is engaging, emotionally satisfying, well acted, and much more layered than I expected from the premise.
If you like character-driven stories and strong chemistry but are hesitant because of the zombie element, I would still recommend giving this one a chance.
