Query: I don't understand

I love Jason Bateman, but I really don't understand why he made this film???? Obnoxious and gross does not NECESSARILY EQUAL FUNNY. When switching places movies happen, isn't the point for the characters to experience something they've never experienced before??? How much of a stretch would it be for a young married guy to - Oh My Gosh - imagine what it is like to be a single guy?! Wasn't he single not that long ago? They might as well make a movie about a college student who magically becomes a high school senior!!!
