In fairness, Erik, it doesn't have much competition in that department.
Okay, yes, I just outed myself - I am emphatically NOT a Trek fan. And...I loved this movie. It succeeds brilliantly despite its heritage.
Even as someone who doesn't like Star Trek, I picked up most of the references and in-jokes, too. They're so much a part of our culture that I absorbed them by osmosis, just from being an American.
It also pointed out how truly awesome the Star Trek universe can be when they ditch all the campy stupidness.

I wish there was some effort to explain what the heck "red matter" is, beyond just "magic black-hole juice". I also wasn't clear on why they had to drill at all, let alone down to a planet's core, to destroy a planet with it. Seems like a black hole would be equally devastating on the surface as it would be at the core.
And...how could a supernova possibly threaten an entire galaxy? And how would turning the supernova into a black hole have saved the Romulan home world?
Yeah, there's still a lot of stupid crap in there. But there was enough pure awesomeness too that it hardly matters. :-)
