Parasyte; Awesome anime in general, quite original. The ending, I did not like, though.
Death note; Amazing, but once again, the ending wasn't satisfying.
Tokyo ghoul; Some things could have been changed, but quite good. The first season was a lot better than the second, because it followed the Manga. The ending in both seasons were cliffhangers, they were breathtaking. Warning: Do not watch if you are against extreme brutality, or drama.
Future diary; Really enjoyable, if you like a shit ton of plot twists and not knowing what the hell is going on. The start was a lot better than the ending, and they should just have kept it that way, the ending was a huge plot twist in itself. All in all, it was ok.
Blood lad: It was ok, the ending wasn't good enough, it just ended, without making any sense. Unnless there will be more seasons, it's not good enough.
Sword Art Online: One of the best I have watched. Really liked both the graphics, and the plot. The ending had absolutely nothing to do with the series, and I suggest not watching the last 3 episodes.
I'll add more to the list when I can.
Anything I should watch that is in the style of these animes?
PS: I love brutality, crime, mystery and stuff like that, as long as it is NOT censored, or doesn't contain a lot of plot twists.
