You make a nice point about Walking Distance (and others like it); I think Time Enough at Last just hit me harder the first time I saw it, for whatever reason, and that's stuck with me. Then again, a lot of my favorite movies are horror movies, even when I know what's coming and when. (Maybe I'm just getting forgetful in my old age.)
