I recently noticed that Ebert and Roeper have started showing the running time of a movie when they first start showing a clip.
Hard to tell if that's to satisfy people who need to know when to tell the babysitter they'll be back from the multiplex. Or maybe it's for the old folks who don't want to or can't sit through a three-hour flick and have to make the early bird at the local seafood joint after the matinee.
Whatever the reason, it would be lamentable if more people chose movies solely on the basis of how much time they'd have to invest. There are three-hour plus movies where you never look at your watch (Dances With Wolves and Titanic come to mind), while there are 80-minute jobs that feel padded.
Given all the dreck Ebert and Roeper have to sit through so we don't, it's a safe bet the running time
