What2Watch: The Goliath Of Prime Time Crowns A David

For all the attention given to the alleged mass decline of American Idol this season, the show is still topping the ratings by a comfortable margin -- it hasn't suffered any more slippage than any number of veteran shows this spring, as normal viewing patterns haven't returned after the strike. The Idol formula is still irresistible to millions, even as the producers seem intent on sabotaging themselves with strange decisions like the Cliché Overusers Full Employment Plan (you heard me, Randy and Paula) and the show's sudden aversion to having the singers perform any contemporary music.

Tonight, the troubled 2007-08 television season reaches its end, climaxed by the year's traditional cheeseball highlight, the Idol finale (Fox, 8 p.m.). This always resembles some sort of insane special from 1977, with singers wandering on stage to sing a note or two with the starstruck contestants, duets with dead people, random shots of David Hasselhoff in the audience, and enough confetti to bury a moderately sized town. After all this, either David Archuleta or David Cook will take home the crown, and it seems to be legitimately up for grabs. The judges' attempt to steer viewers toward Archuleta last night was unusually blatant (if somewhat merited) and may have provoked a backlash.

Boston Legal (ABC, 10 p.m.): Now that we know this perennial bubble show is down to its final thirteen episodes, we might start to see some movement towards various plot resolutions, though since the cast is continually changing I don't know what that might amount to.
