I went to the cinema and i was afraid, i thought it was going to be something way overdone but the first 10 seconds were enough for me. I was going to love it. The special sound when you see the camera moving from the kelvin and the effects and then the battle with the the torpedoes shooting and the impacts. (oke i hated the missiles of the narada a bit but if it were pulses or torpedoes, the kelvin was instantly destroyed).
At the end of the movie it was like "holy shit, this was a star trek movie!" i looked around and everyone was really saying: "mmmh good movie! / Cool effects bro! / Never knew star trek was like this! "
I only heard positive comments.
When i went back i told my dad about it and he was sceptic (he started watching the tng, ds9 etc etc). So i went for a second time with my parents now and my friend and at the end he just said: "god damnit, this is gonna take a long time when it is out on bluray!!"
He loved it too, and i don't care about the nacelles of the ships or so, it is different, and it is good that it is different!
