the first episode will eventually confuse the viewers due to the extensive cast that's almost immediately shoved down their throats and the shifts from one timeline to another (1930, 1931, 1932) would sprout more questions than answers yet, as the story progress, characters are fleshed out in their color, their roles are defined well and their interaction with one another is emphasized. As anime with a huge cast that has relationships with one another IS hard to do, it was surprising how Baccano! managed to pull it off.
the jazzy music of the anime especially the intro Guns and Roses by Paradise Lunch fits the 1930's setting of the story.
overall, with the extensive cast, sequencing of scenes, great story (if you can follow the story's pace that is), Baccano would be a good treat for you.
