Not your best.
It really didn't parody anything in specific; someone could just switch Reach for any other amazing but hyped game and the flash would be about the same.
Other than that, it's not exactly funny. The extreme emotion and grunting works decently when in tandem with an actual joke, but it fails at any entertainment value.
I don't honestly know why someone would put artistic effort into something that's not of any substance in a comedic way, if that is their goal in the first place.
Please find this review useless -- It only diminishes your 10 stars and hasty comments.
