I tend to enjoy the series put out by HBO and this one is no exception. Buscemi does a great job as the anti-hero and there is plenty of violence and titties to satisfy my inner thirteen year old. The 20's are far enough way (nearly 100 years) to be nearly mythical so it's probably a good setting for another series. America was going through a moral crisis and had just finished up one gruesome war.
The main Prohibition agent is a little creepy, but perhaps that's just great acting.
I highly recommend this series and will watch the second season.
