Considering the overall rating I've seen everywhere is like a 80/100 or 8/10 - 4/5, I don't know why all the reviews are so negative? I don't even get most of the complaints.

I watched this because I love unique eyes. Any time a character's eyes are heterochromatic, or their eyes change due to an ability or emotion, so when I read the summary and I saw the trailer with the MC's eyes having these cool-ass blue glyphs in them I was instantly sold, especially because I like action dramas.

As I watched I got invested in the characters and story. Are there stupid things that happen in this show that frustrate the shit out of me? Yes of course that's literally any media you watch, but it was literally only one thing where I went 'genuinely why', but it wasn't the writer's fault.

I liked the characters (The main antag was good at being genuinely psychopathic and I've never- experienced that before in media), I liked the story (It was a mindfuck and there are so many plot twist I never saw coming so it didn't get boring and predictable), I didn't really pay attention to the music but when I noticed it, it fit really well, the acting is great I would feel emotions off of characters and understand why or even just see it without words or large shows of the emotion (again the main antag was- brilliant. Gave me chills and I couldn't stop mentioning the fact he was insane out loud while watching it), and I just genuinely enjoyed this show.

If I ever rewatched it, it wouldn't be for the story, most of the plot twists don't give you room to rewatch it and have the same kind of shock value but I'm sure you could enjoy it regardless. I would probably end up rewatching it for the eyes and characters alone.

Overall it's not that bad of a show and it's certainly not the worst drama of all time, I've seen that and it's unwatchable. People are so dramatic in declaring this the worst drama they've seen. You must not have seen many drama then lol.
