Boardwalk Empire is a brilliant show that unfairly gets shuttled behind Breaking Bad and Mad Men when we're talking about the elite crop of TV shows. But I've written on this before. What you need to know is that there's still time to watch the three seasons—including last year's brutal Gyp Rosetti-fueled bloodbath—before the show returns on September 8. And stay off of Wikipedia. While you might want to know the fates of the many real-life characters that make up Boardwalk, this is the kind of show that excels in intricately laying out the consequences of each gangster's decisions. Your patience will be rewarded.
