Dead rock stars! Sex on tiger skins! A drug kingpin and his love of animals! Why, it’s just another week of movies on Sundance Channel. Here in New York City we’re cruising into springtime, but things are pretty dark on TV. It’s cool if you want to go out and frolic in the sunshine (and booze it up on Saturday), but make sure to set your DVR to catch these films. And stay away from girls in wigs.
