Friday Night Lights (8pm, NBC) - This "new" season of "Friday Night Lights" already ran on DirecTV, but it's making its NBC debut tonight. I beg you to watch. It's a really fantastic show, but chronically under-appreciated and under-promoted by its network. Tonight's show picks up where Season 3 left off: Coach Taylor (Kyle Chandler) has been fired from the Dillon Panthers and must start over with the raggedy East Dillon Lions, over on the more diverse side of town. And even though they've graduated, FNL favorites Matt Saracen and Tim Riggins are still around and still prominent in the storylines. Coach is at a totally new school, so there are a few new cast members, too, with the standout being Michael B. Jordan, who also played Wallace on "The Wire" ("Where's Wallace at? Where's the boy, String!?"). Watch it.

 Kitchen Nightmares (9pm, Fox) - The stubborn owner of a Danish eatery in Miami doesn't want to update anything (then why did he invite this show to his restaurant!?!?), but Chef Ramsay finds something in the cooler that causes him to shut the place down during the middle of dinner service. I don't even want to imagine.
