I don't usually post others' best-of/essential film compilations, since there are too many of them to keep track of, but Bill Hader's list from Poking a Dead Frog is really impressive. Hader is quite the cinephile, and it's a nicely varied set of films. Mostly I just wanted to see how many I'd already viewed, and it's hard to beat Letterboxd for figuring that out. :) (For the record, I've seen 135 of the 200, so I've got some work to do!)
