SPOILERS AHEAD:
There are so many loose ends in this movie. If the Ice Man really did come from a much earlier civilization, what happened to all those buildings in that civilization? Why is that man the only proof of the civilization?
And about Andy? At first, Jack is angry about him receiving the experimental treatment. But at the end, he's happy God made him a continuation of a long-forgotten civilization. Jack's not even worried about Andy possibly dying like the Professor did.
I thought the scenes with the angry monkey were funny. But on the whole, this movie was very sloppy. Kinda like if Rain Man was a sci-fi B-movie from the '50s, directed by some orangutan.
