I thought we agreed no 70s pornos. 
It's not a porno! (Okay, maybe it is. Just a little).
But it's got super cheesy 70s special effects. And it's genuinely funny. And it has robots so awesomely awesome, I'll never be able to rip them off and put them in a Barn Runner game and still have a clear conscience afterward! It's the greatest movie since... well... ever!
