This cancellation makes me sad, but I can't say I'm shocked.

AMC's "Rubicon" was a really smart thriller about smart people solving complicated mysteries. But it wasn't exactly action-packed. It didn't have any explosions or car chases or graphic violence or explicit sex scenes, so not that many people watched (there was one not-very-graphic torture scene, but it was too little too late for viewers). It's a shame.

At least they got to close the book on the main mystery that provided the plot for the season, although I was curious about how the evil consortium was gonna snuff out the newly clovered Truxton Spangler.

Now let's get James Badge Dale on another good show stat.

Extreme Makeover: Home Edition (8pm, ABC) - The man who created the "Move to the Groove" dance program to help combat childhood obesity gets help rebuilding his family home. Derek Hough, Mark Ballas, Tony Dovolani, Chelsie Hightower, and Anna Trebunskaya from "Dancing with the Stars" help out.
