The Big Lebowski = over-rated
National Lampoon's Vacation = not funny at all. any movie with Chevy Chase as the lead is not funny at all.
Annie Hall = are you kidding me? blech.
the rest of the list is ok. not sure they are the 25 best of all time, but they're all worth an occassional view i suppose, though i've never had any interest in seeing the 40 Year Old Bob or Some Like it Hot.
