You have to see the movie — the trailer doesn’t do it justice.
There are a lot of pieces that are just over the top silly. But the premise is great: Survival rewards fecundity and the trend is that smart and learned people are having few, if any, kids, while the dumb are breeding like rabbits (remember these are trends, not statements that people with a lot of kids are dumb nor that people with few or no kids are intelligent).
Project this trend across 500 years and you end up with a pretty dumb populace. When an average guy from 2005 (or so) wakes up after cryostatsis, he is the smartest man on the planet.
You have to have a little patience with some parts, but afterward you will probably find it is one of those movies that is deeper than what you saw, funny on a deeper level, and a perfect analogy for places like, say, Greece.
