I consider this the worst of the Apes sequels :(
I love all of the late 60s/early 70s PoTA films BUT if forced to pick a least favourite - it would have to be THIS film.
The telepathic mutants were way too silly and seemed out of place in this series.
That said, I do admire how bleak this films is. In fact, how on earth did a film like this get a G rating? I originally watched this when I was nine and I had a lot of trouble sleeping.
Escape is the best sequel.
