Robots don’t work that way, magnetism doesn’t work that way, coherent stories don’t work that way. Also; this would have been the best movie ever made when I was 10.
There’s also a sequence where apparently they get robo-baked, they face an angry toastertron which honestly doesn’t do much, and there’s comic relief with a robot spider for some reason. This movie answers the important question, “what if we got real baked, watched a batch of Gwar videos, and decided to make a movie?”
You know dude it’s been established that you don’t have to SAY “pew pew pew” to use your optic ray. This is like that part in Ep II with the droid factory, except I could figure out what was going on in Ep II.
