Story:
Like I said, all the characters act independently of their own will and interact in unpredictable ways. The closest I can come to explaining it is something called a ROC Survivor Contest, where ten characters, each written by a different author, come together to affect the plot and move the story forward. It's also very intricate; pay attention to the dates, because they WILL matter.
Art:
It's pretty darn good for a smallish animation studio. Despite the vast amount of characters, I had no trouble telling them apart; and, might I add, not just because they had different hair colors ;) Their attire is also comfortably designed around the era of the series as well.
Sound:
I didn't remember anything bad about the voice acting or background music, which is good. The OP remains one of my favorites of all time, and voice actors seem suited to their role.
Characters:
Here's where the series really shines. All the characters are so unique, so different, from varying backgrounds and social classes, that it's delightful to watch them interact with one another. There's the old, the young, the old young one, and so many more. There are characters you will hate (like Szilard) and others you will adore (Firo and Ennis! Plus Jacuzzi.) There's someone for everyone. :) They all have depth as well, and you can see their code of ethics through their actions.
Enjoyment:
This is one of the few animes I have marathoned. Believe me, 13 episodes fly by very quickly when there's so much going on. So if you have a night free and don't mind staring at the computer for a few hours, watch Baccano!
