I've divined two things from this list, 1. I need to see more of the classic staples (Citizen Cane, All Quiet on the Western Front, Sunset Blvd, Ben Hur, etc. And I really need to invest some time in watching the Charlie Chaplin movies if I'm going to call myself a movie buff) and 2. Recency skews a lots of the more modern movies into this list, because there's a lot of crap in here. The only Batman movie that should even sniff the top 250 is the Dark Knight.
I'm just fuggin' ecstatic that Avatar isn't on this list.
those are the ones that I picked up...that most have not seen.
I took a cinematography class in college and we watched many of them.....even the Chaplin movies. They are classics.
