Baccano! is one of the first anime series I watched via internet when it was airing and it'll be my first review on here. I never read the novels, so I won't be able to compare the anime to the original work, but even without it, this is an amazing series.
I thought the abnormal order of the story and having 3 story arcs at the same time was kind of confusing at first, but later I got used to it and in the end I loved how it was uniquely structured.
The story is really interesting, so you must check it out yourself. I'm not being lazy to write the summary or anything, I swear. :'D
THE CAST WAS AWESOME. It made me fall for Yoshino Hiroyuki ( I think Firo was one of the first of his major roles). And everyone else for that matter. XD
To be honest, I think Baccano! anime was 124346 times better than Durarara!! anime because the story is simply stunning and too awesome for me to handle. (Not that Drrr!! sucks, but 12-13eps/3vol of novels are much better than 24-26eps/3vol)
Anyways, I'm definitely re-watching this soon because I found the complete DVD set at the local library. Booyah! It's one of those series that I should watch once in a few years. 8D
