If you like Terminator movies this one is much better than the last 2. The special effects are good but the ending scene is just not believable. Go for the special effects and hope this is the end unless we can get Arnold back - but for plot and just good movie going I would recommend the new Star Trek over the Terminator.
I am a 47 year Trek fan and this was the best Star Trek ever - I must admit it was better than all of the TV episodes and movies combined. We finally get the Spock we have been waiting for for almost 50 years - I hope this cast and crew last a long time into the future. Great job!!!
