I'll start with the obvious, even though I know I should try a little harder to think of something more original. But come one, this movie is great.
2) E.T: The Extra-Terrestrial
I can't not go with this. E.T holds a special place in a lot of people's hearts. It's another typical pick, but it would feel wrong to leave it out.
3) Space Jam
I fucking love this movie. I don't care how ridiculous it is. How can you not love little aliens possessing some of our favorite NBA players?
