The story follows three different groups through generally different time periods (at points), but meshes things together to the point where your mind will explode. This can make the story hard to follow, especially for someone who isn't expecting it, but if you feel that you missed some things along the way (like I did), a second watch is totally do-able, and perhaps even recommended. The plot and storytelling mechanics really deliver a gripping ride.
There are a LOT of characters in "Baccano!" -- certainly a risk for a show that's only 13 episodes long. While clearly some get more screen time than others, each character is fun to watch. You can see them grow throughout the story and their interactions with other characters, making them seem very real, and very relatable. (Special shout-out to Isaac and Miria, who TOTALLY steal the show in every scene they're in.)
The soundtrack was composed by Makoto Yoshimori, who captures the high-swinging Jazz of the time period with grace and intensity. There aren't a lot of tracks on the soundtrack, but everything that is there fits with the show's sense and style perfectly. The OP is a MASTERPIECE, while the ED is alright. I don't know how the Japanese voice acting is, but the English dub is probably the best dub I've heard. The accents are ON POINT for every character, and are masterfully done.
The animation by Brain Base is fluid with great character designs. It's consistent through out the entire show, and really brings the city and its inhabitants to life. Coloring might feel a little off at points, but I believe that's purely subjective.
Overall, "Baccano!" is a stylishly fast-paced show that really captures the true characteristics of brilliant storytelling, characterization and animation.
