Not to mention that it's very hard to tell an exploration-of-humanity story in a movie. Mostly, people go to cinemas for entertainment. This was very, very entertaining. Besides, looking at the people that complain about this movie, they are in general the same group of people who were 'predicting' that this movie was gonna suck. Self-fulfilling prophecy anyone??
I sincerely doubt that most Trek-fans talking shit about this movie went in with an open mind.
