I give it a D-. I thought visually it was nice. The story was unoriginal. There were so many plot holes I don't know where to begin. It was a good action sci fi film but it wasn't Star Trek even with its little homages to prime universe Trek. I just think JJ Abrams is more suited for Star Wars type films. I cannot get used to that beer factory engine room or the bridge with a window/view screen with light glares bouncing off it. Sorry, as much as I love Trek I cannot get into this version.
So, I suppose ST:TMP (being unoriginal as it was a remake of the perevious episode "The Changeling"; as well as being full of p[lot holes) "wasn't Star Trek" either?
