Mr. MacRoss and I just returned from a prescreening of the new Star Trek movie.
Let me preface by saying I am a huge Next Generation fan, but never watched more than a few episodes of the original Star Trek (though I have read and heard much about the original) and very little of Voyager and Deep Space Nine. This is also the first Star Trek movie I have ever seen. This movie was by no means "good" in the film student critique sense, but it was filled with camp, action, in jokes, and cameos. I really enjoyed the film and will probably see it again in the theatre (I am looking at you, Uglyfred).
Spoilers: The movie centers around the plot device of time travel and creating an alternate time line (not a new device for Star Trek by any means). This allows the writers to step away from canon a bit and create an intense and emotionally charged context for the Enterprise team to come together. IThe film is not subtle in any way. The acting, writing, plot, and soundtrack are over the top and make as many inside jokes as is possible. We laughed through a lot of the film (even at the dramatic death of a red shirt). Nemoy's appearance was fun, but honestly, the film seemed to drag the most when he was on screen. This may be a product of it being some of the few scenes without combat or action.
Overall, I think this is pure fun and well worth a watch. The bravado is such that it would make Rym look meek (and that in just the first two scenes).
Edit: The casting was spot on except in one instance. They cast Winona Ryder (a 38 year old actress) to play Spock's mother. The casting was glaringly poor. They should have gotten an older actress rather than age her.
Also, there are a few points where the CG on alien faces is painful, but most of the effects work.
