What to Watch Tonight: The Pretty Little Liars Finale, Hawaii Five-0, and Being Human

What to watch on Monday, March 19...

Mondays are a time for elegance. Rather than throwing on your work khakis and trudging to work, why not put on a festive garment and gallivant to work? Rather than sipping day-old coffee from a Garfield mug, why not sip day-old coffee from a champagne flute? Just have fun with it, basically! Speaking of fun:

SEASON 2 FINALE, 8pm, ABC Family
Pretty Little Liars
Well, here we go! Tonight Pretty Little Liars finally gets its Who Killed Laura Palmer? moment when we'll finally learn the identity of the dastardly madman (or woman) "A." Tune in tonight to watch the titular liars get gussied up for a masquerade and find out whether the person who's been making their lives so rough lately is an evil twin, a terrible friend, or just some random spirit dude with long-stringy hair who occasionally possesses otherwise ordinary suburban dads.

Dancing With the Stars
What more needs to be said about this thing? How about the fact that this season Jaleel White will be embodying the white-hot coolness of "Stefan Urquelle" nonstop for our viewing pleasure? No? I got nothin'.

10pm, CBS
Hawaii Five-0
Crossover alert! Tonight Ed Asner appears as the same character he played in the original Hawaii Five-O (with the letter) and this episode will actually incorporate some of that footage. Okay! Also, McGarrett's sister gets arrested for allegedly smuggling $20 million in diamonds, but which of us hasn't had to deal with that situation?

10pm, NBC
The musical's really rolling right along as tonight it'll be workshopped in front of potential investors. Meanwhile Ivy's former Broadway-star mom has a negative influence on her mental game and Karen must decide whether she should do the workshop or do whatever else Karen does. Plus some other relationship stuff that you will be astounded to learn you don't care about. (Maybe, I'm not psychic.)

9pm, Syfy
Being Human
In "Dream Reaper," Sally finds herself imprisoned in a dream world by The Reaper. Yikes, that is NOT Sally's idea of a vacation. Keep your chin up, girl!
