This movie, while silly, is enjoyable.
shareRare case of something where I've seen the original and the MST3K versions though that was many years ago and I can't say much about the film. Anyone who had already seen "Planet Of The Apes", or who found it strange that every character spoke intelligent English, had zero reason to find the ending a surprise.
My own view about movies dealing with cavepeople is that once you've seen Raquel Welch in "One Million Years BC" there's no need to ever see another! :)
