You learn basically everything you need to know about Psycho Goreman[1] in the opening text crawl, when we learn that he comes from the planet Gigax. These are people who are definitely in a joking mood, and want you to be in on it. …for certain values of “you”.

There are these two siblings, and the younger sister is abusive to the nebbish older brother. (10 and 7, maybe?) For example, in their regular game of crazy ball[2], if he wins he gets something pretty regular, I forget what because it was reasonable, while if she wins, he has to dig a hole and then bury himself in it. And of course he never wins.

Anyway, in the course of digging the hole, they uncover the hidden burial site of an immortal dark power bent on galactic domination, and wacky hijinx ensue. It’s astonishing how close this comes to being a family-friendly movie[3]. You would have to change almost none of the plot, but man would you have to change a lot of the special effects.

My point is, you shouldn’t watch it with your kids. Even if it does have a little bit of a lesson right at the end. You should watch it if you like gross-out horror comedy or were ever kind of a dweeb, and if you’re not allergic to children in movies.

[1] PG for short, but since the movie is unrated, I guess they did not compromise on their artistic vision.
[2] Dodgeball but with a Calvinball-influenced ruleset
[3] There’s even a musical interlude in the middle, almost more of a music video, entitled Frig You. Which is a perfect encapsulation of how it’s almost family-friendly.
