This isn't for the faint of heart. I'm talking, "Riker is chef, Trip dies, and Shran's a jewel thief" type stuff. Not kidding. Walk away now. I'm warning you... it's not pretty. Well, it's... whatever it is.
Seriously if you don't like spoilers don't read this because it's probably going to AT LEAST be a big "Holy *&$!%!" moment in the theaters, if nothing else. So you might want to save yourself the surprise. In some ways I wish I had saved it but... in other ways, hmphf. I wanted to know what I was walking into so I didn't break down crying like a little girl in front of strangers.
Funny how Star Trek writers have a habit of causing that lately

SPOILER!!!:
Vulcan is destroyed. Permanently.... Ok, well since you probably want to know HOW the hell that's possible, so you'll probably just go google for spoilers on your own, I'll just say it. It's an alternate universe. Like, it's an ADMITTEDLY an alternate universe.
