This is the most entertaining movie I've seen in quite some time. This movie is well-written with great characters, exciting action, and some laughs. I'm a huge Star Trek fan and saw the movie with a friend who really hasn't watched anything since the original series as a kid, and we both loved it. There are a lot of Easter eggs for the long-time fans, but they've rebooted the series in a way that makes it very accessible to those who just want to be entertained. I highly recommend you see this movie.
As a long-time Terminator fan, I was very anxious to see this movie. I loved the first two films and also enjoyed "Terminator 3: Rise of the Machines." I was cautiously optimistic about this movie, although I was afraid that it might suffer without the starring presence of Arnold Schwarzenegger. Unfortunately, my fears were well-grounded; "Terminator Salvation" was not in the same class as the others in the series. I found the story very underwhelming and simply did not connect with the characters. Although the second half contains some nods to previous films and some good action, it's not enough to salvage the movie. It's watchable, but I'd wait for rental.
