It sucks that it's not a trailer for an actual movie. I'd pay big money for a midnight showing to see that.
I like how it's not pitting the heroes of one franchise against the heroes of the other, trying to prove which set of heroes is objectively better. It's just the protagonists of Star Trek vs. the antagonists of Star Wars. Awesome setup, and the trailer even makes it look like there's a big plotline going on instead of just mashing up random clips.
