Here's the thing: JJ Abrams'
Star Trek a good movie. It is even, I dare say, a great movie - moves along at a great pace, well directed, has amazing special effects, nail-biting suspense, nice dialogue and characterisation (well, as much as you can get in a summer blockbuster), and even attempts to drop in the right Easter Eggs to long-time fans.
So don't think I didn't enjoy it, because I did and very much so. Rest assured that this movie is worth watching, wish the franchise the best of luck and look forward to more movies.
But to really, really enjoy it, as a long-time
Star Trek fanboy, you got to do one thing. You have to throw out any idea that this might be, as the writers and director has claimed, that this somehow is an alternate universe explainable by changes in time travel. Because you can't. If you can ignore it, it's brilliant. If you can't, then... not so much.
I'll just deal with my rantings below. This bit you can skip if you don't care.
