This must be one of the goofiest and most juvenile movies of all time. There are poop jokes, gay jokes, jokes against women and almost everything presented in this film. The meteor story is typically sci-fi/fantasy as a trope on strange unearthly powers granted to whomever possesses the meteorite. This goes back thousands of years through myth. Thor's hammer, King Arthur and the sword in the stone and further back to at least the time of the Greeks.
In this instance it brings change both good and bad to three somewhat lovable hicks somewhere in the American South, which is instrumental as the perfect stereotypical setting for this kind of juvenile humor.
This film is well worth watching. It's clear the cast, writers and producers poured their hearts into this childish but feel good by the end movie. However it also concludes with the possibility of a growing danger brought on by one of the film's antagonists.
All in all I highly recommend this unforgettably weird but worthwhile entertainment extravaganza of poop jokes and gay jokes et al, done with all the exuberance of smarter than your average juvenile delinquents.
