Top X Movies By Category

I have just been looking through movies, and I decided I'd try to finally capture a list or (or two or ten) of my favorites, potentially by genre. That's hard, though, since a lot of them span genres, so some mixing and matching may be involved...

These lists I came up with in the span of about 20 minutes. The pressure of thinking of them has probably caused me to forget a few. So, when I come across some that should have had on here, I'll just come back and change the lists :-)

And, I didn't do top X because some have more than others, clearly.
