WAY more fun than plan 9 from outer space
28 March 2004 | by (where i am is where i am) – See all my reviews

this is one super cheesy film. it's also fun to watch for that very reason. where plan 9 from outer space is just too boring to even laugh at, this film is way off the silly meter.

if the robot monster costume (or his name... "ro-man" LOL) weren't enough, there's plenty of fun dialogue. the pseudo scientific ramblings of ro-man and his boss are hysterical. the plot holes and contradictions are glaring and part of the film's charm. the whole thing plays like it was all made up on the spot and shot in one take.

the extreme low budget props are great too. it turns out that ro-man's video screen is made out of wood. if you live on a planet that can't afford silver spraypaint, then conquering earth sounds like a plan. LOL

this is one bad film that doesn't need MST3K to give you stomach aches from laughing. if you're expecting a quality film, then this one definately isn't for you. if you're a fan of "so bad their good" films, this one is the cream of the crop.
