It's Always Sunny in Philadelphia - Season 2

The second season keeps right in pace with the first, providing the same brand of cynical comedy. The big change is the addition of Danny DeVito as the father of Dennis and Dee. I was worried that he wouldn't quite fit in with the rest of the cast, but those fears were unfounded. He's way more recognizable than everyone else, but he handles the show's unique style just as well. He perfectly captures the crappy father who's now liberated by his divorce and trying to be one of the guys again. Part of the show's success is just the chemistry between the main characters, how they can quickly jump between teaming up and stabbing each other in the back, and DeVito keeps that going.

The second season again covers a wide variety of topics in very crass ways, like welfare, drugs, religion, and politics. There's actually a greater sense of continuity, as what happens in certain episodes can carry over later, which doesn't usually happen in sitcoms. Early on, the gang gets in trouble for something, and later episodes deal with them doing their community service and stuff like that. A whole story arc with the true nature of the gang's parentage comes to a head in the finale, and it's enjoyable stuff. The seasons aren't very long but they're damn funny.
