The Day After Tomorrow with my eight year old.
"AHHH, THE ICE CAPS ARE MELTING!!!! AAAAHHHHH"
I love this movie. Always have. Teaches a lot of good concepts too.
Such as, if there is a polar vortex that is going to drop the temp 10 degrees/second coming towards you, then it is okay to pop into a Wendy's to get warm and cook up a few burgers.
We dropped 20 degrees in 15 minutes on Saturday. That's gotta be close.
