TONIGHT'S MUST-SEE

"The Eternal Sunshine of the Spotless Mind" (2004), 8 p.m., cable channel E. Joel has a clear mind, unsullied by a painful past. But why do shards of memory pop in? And who is this appealingly eccentric stranger? Here is another wondrously odd script by Charlie Kaufman, who wrote "Being John Malkovich." Director Michael Gondry got perfect performances, led by a superb Kate Winslet and a refreshingly restrained Jim Carrey.

TONIGHT'S MIGHT-SEE

"Heroes," 7-9 p.m., NBC. If you missed the season opener Monday, here's a second chance. High-voltage events are packed together. Complicating things is an overload of abilities. One person sidesteps a bullet; another steps into an alternate body. Two spring back to life. When characters lack limits, the drama starts to seem pointless.

OF NOTE

"Primeval," 2 and 3 p.m., BBC America (Oceanic Digital Channel 341). Things have been tough for Nick lately. He learned that his long-missing wife is an opportunistic cheat. He also returned through a time/space portal into a world kind of like the one he left, except that his new girlfriend Claudia never existed. Last week's episode (rerunning at 8 p.m. today) had a new twist; this week's has giant worms.

"Samurai Girl," 3-9 p.m., ABC Family. Here's the full, six-hour miniseries. A rich girl discovers an epic destiny. This looks great, but has some wooden writing and acting.

"CSI: Miami," 7 p.m., CBS. Horatio's son is missing after taking part in a prison escape.

"Criminal Minds," 8 p.m., CBS. The search for a cannibal creates a crisis of faith for Morgan (Shemar Moore).

"Chris Rock: Kill the Messenger," 7 and 10 p.m., HBO. Some of Rock's stand-up specials have been masterful. This one combines concerts in New York, London and South Africa.

"Law & Order: Special Victims Unit," 9 p.m., NBC. Here's a quick rerun of Tuesday's season opener with Sara Gilbert as a traumatized rape victim.

"Saturday Night Live," 10:29 p.m., NBC. Anna Faris hosts, with music by Duffy.
