A review of season four of It’s Always Sunny in Philadelphia, which ended  November 20th. You can watch full episodes at FX’s Web site.

Since it first aired in 2005, It’s Always Sunny in Philadelphia quickly became one of my favorite shows. While I thought season three was very funny, I was hoping that season four wasn’t going to be more of the same. I was not disappointed. There is not a bad episode this season. The writing and acting seem more refined. The jokes are still funny, and the timing is always perfect. The characters are really coming into their own.

My only criticism is that the final episode was not a rock-solid season finale. In fact, I had to make sure this was really the season finale. It’s not a bad episode. It just didn’t have the same kick as the season three finale.

According to Wikipedia, FX Networks has ordered enough episodes to last a couple of more seasons, and the main actors have all agreed to remain on the show. So, for the next few years, it will continue to be Sunny in Philadelphia.
