Baccano! is an anime I thoroughly enjoyed. I watched only because I loved Durarara!! and well, if it's by the same author, it's bound to be good, right? I actually stopped after 3 episodes because it was confusing. Ironic since I loved Durarara!! so much.
Plot: 10/10
The gist of it is, 3 story lines are all tied together. It's about trains, immortality, and the mafia. It's hard to follow at first because Baccano! changes point of view so much, but after a while, the pieces come together. There's a great sense of realization you feel near the end. It's that feeling, I think, is what makes Baccano! so great. It's a unique storytelling I enjoy a lot.
Art: 9/10
I'm very fond of the art and animation. There were nice action scenes.
Characters: 9/10
The characters were great. There are so many of them, so there isn't any time for character development. But, I really liked all of them. Each of them had their own weird vibe.
Music: 10/10
I like jazz. The soundtrack is jazzy. Good, good.
After watching, my conclusion is that Baccano! is definitely better than Durarara!! but I love both. I recommend to anyone who needs something to watch.
