What to Watch Tonight: Terra Nova, HIMYM, and Castle

What to watch on Monday, October 31...

Oh no, it's Halloween on a weekday! What do we do? Candy, first of all. Tons of candy. Also, maybe, some television? (With the lights off, obvs.) Sounds good!

8pm, Fox
Terra Nova
Uh-oh, the colony's starting to get intense, you guys. Tonight Jim and Taylor investigate Terra Nova's first-ever murder, plus Skye decides to help Josh reunite with his girlfriend (from the future). Also: Zoe plays with a dinosaur egg. Makes me kinda nervous, but whatever, that's Zoe for you.

8pm, CBS
How I Met Your Mother
The bizarrely ubiquitous Katie Holmes appears tonight as the legendary Slutty Pumpkin, the much-pined-for lass who Ted has searched for ever since he lost her number after a Halloween party years ago. And because it's a Halloween-themed episode, Holmes will have a hollow, haunted expression in her eyes the entire time.

9pm, Fox
Tonight a CEO falls ill after making an unpatriotic decision to outsource his company to China. Plus Park finally faces the music for having slugged a doctor. In her defense, [adorable mumbling].

10pm, ABC
While chillin' at a bank with his mom, Castle suddenly finds himself a hostage in a bank robbery! Then, when Beckett attempts to deal with the situation, a dickish hostage negotiator becomes a real pain-in-the-butt for her. It's like, jeez, is it Friday yet?

Rock Center with Brian Williams
Congratulations to Brian Williams on his newly minted primetime news magazine! Broadcasting out of Rockefeller Center, Williams will bring us only the most straightforward, trustworthy, and blandly handsome of the week's important news items.
