Weekend TV Preview

Tonight, Grizzly Man -- the bizarre and compelling documentary by Werner Herzog -- is on Discovery at 8 p.m., the crazy teen soap South of Nowhere (it's like The OC on crack) winds up season one on The N, and of course it's SciFi Friday, with the terrific Battlestar: Galactica focusing on Starbuck. Saturday, I'll be watching bullriding on NBC at 4:30 as they follow the PBR (bullriding is the new NASCAR), but the big news is Steve Martin hosting SNL with musical guest Prince. Another chance for the sketch show to convince us that two good skits out of 237 in a season is a reason to tune in weekly. And Sunday is the Super Bowl followed by a new Grey's Anatomy. I'll be taping it all so I can fastforward through the football and watch the commercials, hear Aretha sing the National Anthem and listen to the Stones at halftime.
