I felt much the same way when I watched the film. Trouble is, the forum on which I chose to share my opinions (the SFX forums), was filled with people who ADORED the film. They thought I was trolling because I didn't like it! I suppose I wrote in an over-the-top way on purpose. The bit you might agree with:

"This is the most badly-behaved and unprofessional Starfleet crew I have ever seen ... Some goofy things have happened in Starfleet over the centuries, but I really can't believe a young third-year cadet can become captain of the fleet's flagship purely by being a magnificent bastard. I appreciate a few moments where Chris Pine truly gave brief flashes of a young Bill Shatner, but I spent most of the film thinking "What a prick.""
