Short but Sweet
I loved the dramatic buildup to the final killing shot. I'm not going to do my usual in-depth review, because I generally save those for longer, more involved works. I figure if someone wastes a month or two making something, I could spend 10-20 minutes reviewing it at least.
Anyway, the joke really could have survived on its own. My only complaint is the whole "the Star Trek universe..." thing at the end. It was unneeded and somewhat implied in the movie. That kind of detracted from the funniness of the thing as a whole.
