What we're watching: Only one season finale tonight, as House ends their season with a bang, literally. The Eastern Conference finals are here, and it's the same teams as last year, Detroit vs. Miami. They went all seven games last season, what will it take to get to the finals this year?

On ABC Stephen King's Desperation takes center stage, maybe this will be better than every other Stephen King adaptation (except Misery)...maybe not. The miniseries 10.5 Apocalypse also comes to an end on NBC, but we may give WB's Pepper Dennis another look at 9 p.m.

Our traditional high-def listings continue below.
