Critic's corner
The Mentalist 9 p.m., Channel 4
The season's biggest dramatic hit closes up shop tonight with an episode about Red John. He's the serial killer who murdered the wife and daughter of Simon Baker's Patrick Jane, and he's trying to lure Jane into a trap. I've really enjoyed this show, despite its procedural predictability. Baker has expertly walked the line between arrogance and brokenheartedness.
Painted Babies at 17 10 p.m., TLC
The title is just too good. When you see little-girl beauty pageants, the kids do look like painted objects - dolls smeared with makeup and big Vegas hairdos. In this documentary, filmmaker Jane Treays revisits the girls she profiled in her film "Painted Babies."
