Frozen - because while I wanted to like this movie, I just...didn't. Okay, actually it was having songs in the movie that didn't need to be there simply because they needed songs. It was like, let's sing this conversation instead of merely speaking it. Bleh. Anyway, this video really outlines all of Frozen's sins...and it's hilarious.
Armageddon - I haven't actually seen all of this movie, but oh, is Cinema Sins video on it funny!
I highly recommend checking out their other videos on movies. Awesome stuff...and addictive. :P
