I just watched Time of the Apes, a horrible Japanese knock-off of Planet of the Apes. Except in this version, a woman and two children get accidentally cryogenically frozen and travel to the future where monkeys are in charge and there seems to be only one human left. After running from many people in bad ape suits, they escape with the help of a flying saucer. As soon as they’re about to find out who controls the saucer, they find themselves waking up back in their own time. This is never explained, you just have to accept it.
I rate this movie 19 empty seats, one for every year after Planet of the Apes was filmed.
