WHEN YOU'RE A GLEEK: (Apologies to the "Jet Song," as we prepare our audition for West Side Story — or in Kurt and Blaine's case, West Hollywood Side Story?) The best way to enjoy Glee these days is to accept and even when possible to embrace its imperfections. Kind of like the way the characters get past their own perceived shortcomings and insecurities to embrace their inner star. (Just watch Mercedes blossom this week into full-blown diva mode, for better and inevitably for worse. It's pretty thrilling.) You can tell, from last week's and especially this week's impressive "Asian F" episode (Fox, 8/7c), that Glee is trying awfully hard to improve from the mess of last season. The music is better integrated into story, the story is better integrated into character, and sometimes the characters even make sense.
Tonight's Top Pick: When worlds collide, Fox's cult gem Fringe (9/8c) is at the top of its game. You've never seen a murder-mystery manhunt like tonight's chilling and provocative episode, in which the Fringe team from the "other" world enlists "our" Olivia to cross over to track down a serial killer in the alt-universe — by bringing along the madman's doppelganger from our world, who happens to be a professor specializing in forensic pathology and profiling. The "what-if" vibes are fascinating as the professor — and by extension everyone in the dual-universe loop — considers the vagaries of fate and environment when confronted with "the path not taken." The story is suspenseful, poignant and wonderfully original. And in case you're wondering why Walter stays behind, surrounding himself with a cacophony of music: It may have something to do with that nagging disembodied voice he can't stop hearing. Hurry home soon, Peter Bishop!
