The effects are fantastic, the story is pure fun, some role reversals are great, and you'll come away from the experience completely satisfied ... unless you're simply not a fan of sci-fi or Star Trek and then why would you go anyway? There is a scene where Kirk and crew create a planet of nerds by their actions that's very entertaining early on.
A certain device also appears that us older fans always wondered about ... well, we wondered about its absence. It just didn't make sense. You'll see that late in the film
If you've never seen a Star Trek film before, but would like to, there's plenty here to make it accessible to you. Just find a Star Trek fan friend either to go with you or to explain some of the details to you later. You'll still have fun.
Oh yes, and before I forget, there's also a moral in the story, which should make ardent Gene Roddenberry fans happy. It made me happy for sure.
One more thing ... well, next to last thing, I've been having a stressful time lately. There's a lot going on that has me very distracted and out of sorts. And yet, for about two hours I was thinking of absolutely nothing else than the movie and the intrepid crew of the U.S.S. Enterprise. It was wonderful. It was a relief. It was well worth it.
To avoid giving away anything, I need to stop now. All I'll add is that J.J. Abrams can keep making Star Trek films just as long as he likes and I'll be happy. Of course, with him at the Star Wars director's helm that may not happen ... but it should.
Live long and prosper new Star Trek cast! You did great.
