What was the original ending?
It's on the DVD, but I haven't found a review that really describes it, though one called it "understated," another called it "contemplative," and a third called it "cruel" and specified that it didn't involve Witherspoon staying with Wilson.
My guess: she dumps both of them and rides off into the sunset. But I'd like to know without going to the trouble of renting something that was so excruciating to sit through in the first place.
