If you're a fan of all things Trek, go see Star Trek.
If you're sick and tired of all things Trek, go see Star Trek.
If you don't know what a Jeffries Tube is or how a nacelle works, go see Star Trek.
It was a great movie that really takes what was a tired franchise and gives it a kick in the pants that lets it go in all sorts of directions while still paying homage to what has come before. And there are all sorts of pretty explosions.
There are quibbles if you're the quibbling type and I think that if you're currently reading this in your uniform while taking a break from chairing the meeting of the commanders of your local Starfleet outpost, well, you might not enjoy it as much. That said, the majority of the 'flaws' are nit-picky at best.
The only truly annoying thing about the movie are the lens flares. Holy smokes, it's like J. J. Abrams bought a crate of lens flares and had to use them all up by the end of the film or they'd pull his funding. It's not that they're distracting, but... well, they're everywhere.
