Have you seen JJ's film skyjedi2005? The trailers look amazing and JJ doesn't do much wrong. I just worry that he's a (gasp) Star Wars fan not a Trek fan.
I'll no doubt grab this Special Longer Version, but there's no getting around the fact that the movie is deeply flawed and really has about an hour of story stretched out.
Abrams may have made a better film, you don't know (and neither do I).
