Jerry Bruckheimer movies in general and some Richard Donner movies, at least up until the early 2000's. It's mostly well made good looking mindless entertainment, so the time seems to pass along swiftly, and somehow I can't remember much of them afterwards so they always seem fun when I watch them again. Lethal Weapon 2 is probably the one movie I have watched the most, and it somehow never really gets boring, even if it's not even on my top 10 list
