A very slow paced Mystery and suspense show that isn't going for much.
In general, Another is more about the Gore and Mystery aspect than anything else. The first episodes of the show are INCREDIBLY Slow and Boring. It is only after the 3rd or 4th chapter that stuff starts to happen, and it's just all about waiting for the next Death scene.
It's pretty much all of why you end up seeing each episode.
In that aspect, it does deliver some of (nowadays) most iconic and classic death scenes, but that's pretty much the only memorable aspect of it. And for that, it might should have been a shorter series of OVAS.
The story isn't that much interesting at all. It's fine i guess, but nothing you would remember much of. It's just all about the plotwists and the mystery at best. Characters are basic, and have little to no development or any sort of arc. They are just there to make you wonder "Who is going to die next?" and that's it.
Animation was ok, having some really high quiality death scenes with awesome animation. In terms of art style, i might give them the credit for the color palette being more dry and obscure than every Moe anime of the 2010's. It does match the tone a little bit more.
Overall, not a bad watch, but since it's not going for much, it doesn't have anything going on. Enjoy the gore and that's it!
