Review of K
Honestly, K project isn't that good of an anime. The plot was eehhh and the pacing was all over the place- i wouldn't praise it as a 'good anime'. I personally really enjoyed it because it was deep and quite entertaining, but i know clearly that this anime isn't for everyone and it's understandable why people wouldn't like it. I wouldn't recommend this anime to anyone who enjoys well written plots, but if you're prepared to go in without any expectations and just let yourself go along for the ride, then you should give the anime a go. Before I start reviewing the plot and charactersitself, let's talk about how beautiful the aesthetics of this anime are. If you're afraid the animation and art are going to be similar to Gohand's other works, don't be deterred. The animation and style of the characters is nothing like Handshakers, without any of the shaky animation that makes your eyes hurt. The shading is really pretty, and has this blue sheen that adds a lot to the mood.
The soundtracks and the osts of this anime are some of the best I've ever heard; they add a lot to the mood and some of the tracks fall under lofi. I honestly recommend that you have a listen to the soundtrack even if you don't watch or don't like the anime.
Now, other reviewers are talking how trash the plot is, and honestly, they're right. If you're looking for an anime that has great writing and is plot heavy, this anime really isn't for you. The pacing was truly not done well- even if the anime only had 13 episodes to work with. The ending was extremely rushed, and the plot threads were resolved in a really underwhelming manner- they even forgot to give the villain a motive apart from 'i don't like them'. This completely destroys the mysterious feeling the first half of the anime was building. The first half of the anime was really slow, but personally i really enjoyed that. It built up this tension and this mysterious mood that i adored. Some say it was extremely boring, and yes, they could have written the story better so that they didn't have to rush the ending. The premise was actually really interesting and they could have done a lot better if they fixed the pacing and developed the villains and so on.
As for the characters... they were fine. The writers were really trying to make them feel deep like with Kuroh, but it just didn't work. I'd say that the only character who actually had detailed development was Shiro. The mystery of Shiro really could have been done better. He had so much potential and the reveal was just really underwhelming, but watching him realize he wasn't who he thought he was really entertaining. Much of the tension between the characters were left unexplained like with Fushimi and Misaki (but that was resolved in one of the movies from K: Seven Stories, however a good series should be standalone without having to make the audience watch a movie to know the details). The characters were fine, engaging while it lasted but in the end, are just sort of flat.
One thing i will praise K project for is the mood. The first half of the anime was absolutely beautiful- Shiro eventually realizing he wasn't who he thought he was and the mystery behind the death of Red Clansmen. Although this was broken by the bad pacing, it was somewhat engaging and made an interesting premise while it lasted. The power system and the art/music/mood was enough to carry me to the end.
In the end, to me, K project is a really unsatisfying anime that was really enjoyable. If you don't mind watching an anime you'll easily forget with bad pacing - then you'll get a little kick out of watching it.
