• It’s another big season finale night starting with the much maligned 24 (Fox, 8 pm), which everyone agrees is pretty crappy compared to last year. However, in tonight’s two-hour finale, expect a showdown with Jack’s dad (James Cromwell) and the death of yet another CTU member. (Trying to get a decent life insurance rate while working at this place must be a bitch!)

• Next, it’s the breakout freshman series HEROES (NBC, 9 pm). Tonight, all the heroes gather in Kirby Plaza to stop Peter Petrelli from going nuclear and destroying NYC. (Insert obvious 9/11 metaphors here.)

• And speaking of a dark, depressing future, check out the following trailer for the new Fox series debuting this Fall called THE SARAH CONNOR CHRONICLES (say that five times fast), in which a not-as-buff-as-Linda-Hamilton mom tries to protect sonny-boy from the Terminators of the future (with a little bit of help from a hottie teenage robot… whoo-whoo!).
