I’ve only seen this once a long time ago and decided to watch it again. I really like this movie. It’s occasionally corny but it’s great. One thing that bothered me was the couple scenes of (not too egregious) nudity that show up. I mean, it was the early '70s, but it just makes it less comfortable to watch with other people. They’re short though, and it doesn’t lessen my liking of the film.
I still have to watch The Last Man On Earth, which I expect might be better based on popular opinion.
