The trio behind “It’s Always Sunny in Philadelphia� has cooked up some of the most unpolitically correct humor in the history of TV, but for “A Very Sunny Christmas,� they’ve dialed it down considerably, instead relying on more gratuitous tactics – like language, nudity and gore – to score laughs. Split up into two stories, the holiday special follows the gang as they prepare for Christmas Day. While Dennis and Dee try to teach Frank a lesson by taking him through his own version of “A Christmas Carol,� Mac and Charlie try to cope with the fact that their Christmas memories aren’t as great as they remember them. The episode culminates with a Claymation musical number that features Hermey the Mischief Elf, Sam the Snowman, and the California Raisins dressed up as KKK members.

Though the former subplot definitely has its moments (a sweaty, naked Danny DeVito not being one of them), the latter is easily the funnier of the two, whether it’s Mac losing his temper or Charlie going nuts on a mall Santa. Still, for a show that’s just beginning to earn an audience beyond its cult fanbase, it takes a lot of nerve to release a 42-minute Christmas special straight to DVD. Though you can’t really blame the creators for making this kind of executive decision (this has Fox’s greedy little fingerprints all over it), the show itself really could have been a lot better. Instead, you get a mediocre extended episode for about five dollars less than the cost of an entire season. It’s not exactly a great way to win over new viewers, and certainly not the way to treat old ones either. This is strictly for diehard fans only, but even they may have issues with ponying up the cash for something that FX is bound to air for free eventually.

Unfortunately, I didn’t have the time to put together a list of my favorite television moments before the end of 2008, but that doesn’t mean I didn’t spend an inordinate amount of time in front of the tube. (Come to think of it, maybe my television addiction was the reason I didn’t have the free time to write about the best of 2008. Hmm.)

Anyway, here is a list of seven terrific shows that seem to be flying under the proverbial radar.

1. “True Blood” (HBO)
Alan Ball, the writer of “American Beauty” and the creator of “Six Feet Under,” brings us a series based on vampires in the Deep South. The series is based on Charlaine Harris’ Sookie Stackhouse series of books and stars Anna Paquin — whom I argued, under the moniker of Eli Cash a few years back, would have made a better Penny Lane than Kate Hudson — as a mind-reading waitress in a small town in Louisiana. The first season was excellent, though it got off to a bit of a slow start. Paquin is the key, but her best friend Tara (played by Rutina Wesley) often steals the show.
