Law & Order: Los Angeles (9pm, NBC) - The LA version isn't as good as any of the other versions, and this week's episode where they killed off Skeet Ulrich's character was just plain awful.

Gordon Liddy mustache, and there are great performances from Alfred Molina (bumped down from DA to detective) and guest star Tim Dekay ('White Collar').
