American Idol, Sarah Connor Chronicles, True Hollywood Story

American Idol, 8 p.m., Fox

Can you believe that we are already down to six? My goodness this season is sprinting by. Tonight will not be Lucky 7 for Stefano, who has spent more time in the bottom three than any contestant ever, I think.

Terminator: The Sarah Connor Chronicles, 8 p.m., SyFy

SyFy is offering up a marathon of this short-lived piece of brilliance that aired for two magnificent seasons on Fox a couple years back. If you are a Terminator fan, you probably watched it back then. If you missed it, I highly recommend it. Yes, John Connor gets whiny a lot, but Brian Austin Green is awesome, and I have two other words for you: Summer. Glau.

The E! True Hollywood Story, 10 p.m., E!

Tonight, Sarah Palin. Remember when it was a big deal that Ronald Reagan had been an actor? Those days seem so quaint and old-timey now.
