Watch this, tape that - Wednesday

This week is moving like molasses. Here's what's on tonight:

Holiday specials
"Prep & Landing" (ABC, 8:00).
"Christmas With the Mormon Tabernacle Choir" (PBS, 8:00).

8:00
Tape this: "So You Think You Can Dance" (FOX). You could watch this 2-hour finale live, but if you're like me you'll want to watch the repeat performances of the season's best routines more than once. Go Russell!!!

9:00
Watch this: "Top Chef: Las Vegas" (Bravo). It's the reunion special.
Tape that: "Criminal Minds" (CBS). An ex-con escapes while in BAU custody. Expect the word 'unsub' to be used about 23 times.
Catch it on second run: "Real World/Road Rules Challenge: The Ruins" (MTV). Another reunion.
