Unless you’re in the business, and therefore think Dumb and Dumber is Shakespeare, this is continually surprising in its comical amusements.

It was hard to make fun of the bio-dome experiment, because it was so absurd in itself, so the main focus of comedy here is what you might call the gravitational pull of the place in the first place, and then there are some jokes about it, with a nicely refined ending and a tag that takes the mickey out of the thing.
