“Supernatural” (KWBQ-19 8 p.m.) In the season finale, Sam and Dean try to save their father from returning mystery babe Meg (Nicki Aycox, Jeepers Creepers II). Word is that Meg will stick around next season as a recurring character.
“Ghost Whisperer” (KRQE-13 7 p.m.) It’s supernatural season finale time. While trying to help the ghosts from a crashed airliner, Melinda (Jennifer Love Hewitt) finds herself stalked by an evil spirit. Thank god. Evil spirits are so much more interesting than those touching Hallmark Channel spirits she keeps running into.
“The Tribeca Film Fesival” (A&E 9 p.m.) A&E takes you to check out the haps at New York’s hippest indie film festival. ... If you can call the premiere of Mission: Impossible III indie.
A.I. Assault (Sci-Fi 7 p.m.) A whole host of TV vets (Michael Dorn from “Star Trek: The Next Genration,” Joe Lando from “Dr. Quinn: Medicine Woman,” Alexandra Paul from “Baywatch,” Billy Mumy from “Lost in Space” and Robert Picardo from “Star Trek: Voyager”) join forces with infamous director Jim Wynorski (Alabama Jones and the Busty Crusade, The Bare Wench Project 2: Scared Topless, Scream Queen Hot Tub Party, Sorority House Massacre II ... I could go on). Story concerns some Navy SEALs who are called upon to hunt down two killer robots lost on a tropical island. Just add alcohol and enjoy!
“Inside the Actors Studio” (Bravo 7 p.m.) James Lipton kicks off a new season of “Inside the Actor’s Studio” by welcoming the entire cast of “Law & Order.” Followed, quite coincidentally, by a bunch of “Law & Order” reruns.
“David Blaine: Drowned Alive” (KOAT-7 7 p.m.) I wish. Blaine was mildly entertaining back when he hung out with Leonardo DiCaprio and performed his “street magic” for assorted drunken bar girls. Lately, however, he’s become obsessed with a string of “extreme” stunts. Here’s hoping watching Blaine stand underwater for a week is half as riveting as watching him stand in a block of ice for a week.
Fatal Contact: Bird Flu in America (KOAT-7 7 p.m.) While I admire ABC for ripping the plot for its latest made-for-TV cheese straight from today’s headlines, I do wonder how many thrills can be had from watching people get stuffy noses for two hours.
“E3 ’06 Live” (G4 7 p.m.) G4 jumps into a week of live coverage from the Electronic Entertainment Expo, the largest gaming convention/trade show in the world. Get the scoop on all the new games and next-gen systems clawing their way into Best Buy this year.
“Top Chef” (Bravo 7 p.m.) The thing that bugs me about reality shows/game shows/elimination competitions is what little effect they have on my life. Tonight, America’s top chef will be crowned. Will I ever have the opportunity to eat his or her food? No. So, really, what do I care? ... That said, I think Stephen should win.
