TV tonight: 'Mike & Molly,' 'Red Tent'

The Great Christmas Light Fight
ABC, 8 ET/PT

Why watch videos of wildly -- and depending on your point of view, marvelously -- over-the-top Christmas displays online when you can catch an entire six-episode series devoted to finding the most over-the-top of them all? Michael Moloney and Sabrina Soto return as hosts and judges for the second season of the Light Fight , which pits four families a week against each other to see who can make your spirits and their electricity bills soar the highest. The top prize is $300,000, which should just about cover the decorating costs.

Mike & Molly

CBS, 8:30 ET/PT

This CBS sitcom makes an earlier-than-expected return with an episode that finds Molly coming home from her writing workshop with a big book deal in hand. Let's hope success doesn't spoil our Molly — and that her show pulls back a bit from the sometimes frantic excess that took hold last season. There's a great cast at work here, whose work would benefit from being less broad.

The Red Tent
Lifetime, 8 ET/PT

This two-part adaptation of Anita Diamant's biblical novel concludes. Set in the times of the Old Testament, the miniseries focuses on Dinah (Rebecca Ferguson) and the four wives of Jacob, who gather with the other women of the tribe in a red tent and share stories. Minnie Driver, Morena Baccarin and Debra Winger also star.
