I'm of two minds on this short film. (Note: There's a character who swears quite a bit, in case that sort of thing bothers you.)
The first part of me thinks it's a really cool little film (especially with the maker's note that it had essentially no budget), and I'd totally love to see the rest of RL7's story.
The other part basically thinks that there couldn't possibly be a stupider way to check for malfunctions in a robot, especially an insanely dangerous one with organic brain components apparently harvested from a hapless victim.
Not that this actually makes it less enjoyable, it just strikes me as the stupidest idea ever.
