American Idol (8pm, Fox) - The winning singer is named tonight. Odds are that the winner will be Garner's own Scotty McCreery, but you just. never. know. Georgia's Lauren Alaina has been a strong contestant, too. Before the big moment, there will be a reunion of the Top 13 contestants from this season (I've already forgotten anyone past the Top 6) and the iconic rock band U2 will perform with actors from the "Spider-Man: Turn Off the Dark" Broadway catastrophe. I mean show. Broadway show. One last time, Go Scotty!
The Middle (8pm, ABC) - It's finale night for all of ABC's Wednesday night sitcoms, even the very funny "Happy Endings," which just started a few weeks ago. On "The Middle," Axl hasn't completed his 30 days of community service and Sue has to prove she's never taken a sick day to get a perfect attendance award. On "Modern Family," Jay wants to spend his birthday fishing but his family wants a big party, which leads to Claire and Mitchell getting trapped in the yard of their childhood home and Cameron getting into trouble at the bakery. And in a one-hour finale for "Cougar Town," Travis moves to Hawaii and the gang uses that as an excuse to take a vacation there, though they're really on a mission to convince him to come home. On "Happy Endings," a surprise invitation to the wedding of an old slacker buddy leads Brad and Jane to uncover something disturbing about their marital status, and a depressed Penny asks Derrick to be her date and pretend they're engaged.
Criminal Minds: Suspect Behavior (10pm, CBS) - This one didn't make it, so tonight's season finale is actually a series finale. In this last episode, a serial killer is shooting people in crowded places and Beth's life is threatened when she goes undercover with Prophet.
Law & Order: Los Angeles (10pm, NBC) - It's not a finale, but it's one of the few non-repeats on tonight. In this episode, the murder of a casino worker exposes an argument that occurred before the crime and an admission from the victim's girlfriend that complicates the case.
