We went and saw "Star Trek Into Darkness" on opening night (9 May). I've just come back from seeing it my second time (20 May).
There are two reasons why I delayed posting this review. I had some notes written after my first viewing, but didn't really want to spoil it for American readers (the movie wasn't released till 17 May over there). I also really really wanted to see it again, and figured I'd take more notes that time and end up with a decent review. There may still be spoilers in the following review, but I will keep them hidden like this. (Just be careful where you move your mouse.)
