Well I just got back from watching the film (from the UK) and I thought it was truly fantastic. one of the best films I have seen in a while and just as good as Trek '09 (which is one of my all time favourite movies). Some great twists, excellent performances and it looked visually incredible. For those of you from the US, I would avoid the Internet for the next week as the major spoilers are likely to be flying left, right and centre.
P.s. the short sequence with the Klingons was great with them never looking better.
My only gripe was that I thought the movie ended was too fast. (I.e. too much in too little time) but this didn't ruin it for me.
