I love this kind of movie.
It's one of those things you either love or hate, and a lot of the venom getting tossed at it isn't needed. It's just a movie folks.
Innocent fun.
It's about this alien cop who winds up crashed on earth only to find out he's the size of a ken doll, here.
Lucky he's got his "Ruger," the most powerful handgun in the universe (don't ask). This little thing blasts holes in his foes as if it was a .357 magnum (and, as i recall, it literally blew people apart on his home planet).
It's not Citizen Kane, but it's clever and tongue in cheek. I can actually see a silver age comic book like this.
