Here's the long rant you requested.
This is maybe the first Portal entry in a long time that made me laugh. I've seen many a movie come through the portal about the shitty stuff submitted by bored 14-year-olds. But the fact that this glorifies the crap as well as making fun of it makes it entertaining. Here's the nerd-terminology of the day kiddies: Satire. This movie is a good example.
You forgot something though... skateboards. Skateboards are right up there with stick figures as components for Bad Movies.
And insulting bands that are well-liked by the stupid-kiddie population, like Eminem, is a surefire way to get yourself hated even by those who do enjoy stick figures on skateboards spewing badly-rendered blood. And calling yourself a L337 H@><0R is a good touch too, I really hate that...
Seriously... cool movie. Sorry, but I just cant vote X like you requested...
