Is life one big competition show?

Maybe we're reaching the point where all of life is one big reality-competition show.

That's how it will seem Wednesday (Sept. 15). In one dizzying night, four final champions will be named; that same night, two more shows start and one cotinues. Our VCR's might implode.

TV has always been about feast-or-famine, all-or-nothing, overload-or-wasteland, but this takes it to an extreme. The finales are:

-- 8-10 p.m.: "America's Got Talent" (NBC), a very silly show with some serious talent. I'm especially impressed by the pure-classical beauty emerging from the mouth of 10-year-old Jackie Evancho, but the others -- Prince Poppycock, Michael Grimm, Fighting Gravity -- are also worth catching. You can see their final performances from 9-10 p.m. Tuesday, then vote.

-- 8-10 p.m. (also): "MasterChef" (Fox) which skips the pros and has amateur chefs. It's down to its final four.

-- 9-11 p.m.: "Big Brother" (CBS), which gives someone lots of money, but no particular title. Best roommate? Loudest person?

-- 10-11 p.m.: "Top Chef: Washington" (Bravo). Right after the amateurs get their prize on Fox, the pros get one on cable. To get in the mood, you can watch the previous episodes at 8 and 9.

And then that's it -- except that the same night debuts two more shows. CBS has "Survivor" from 8-9 p.m., this time with an old-vs.-young theme in Nicaragua; Bravo has a new round of "Top Chef" at 11 p.m., this time focusing only on desserts.

Oh yes, the second round of "America's Next Top Model" is from 8-9 p.m. Wednesday, with an elimination you'll be glad to see. Try to keep all of these straight; otherwise, you'll be expecting the models to start singing arias and making cupcakes in the Nicaraguan wild.
