The long arc

I know a guy who knows a guy who walks out of every movie before the end; he says last acts are always a letdown. That's a pretty good point. The part where they're introducing characters and complications can be engaging and novel, while tying up loose ends is more pedestrian. Or maybe writers are just usually people of an age where they have some experience with beginnings, but for endings they fall back on formula. They should hire extremely old people to finish their stories. Of course, then most movies would end, “Where am I? Where's my lunch?”
