Having finally watched the movie, I tend to agree with Ebert. JJ's movie has bits and pieces of Star Trek placed all over, but dare I say that the movie lacks the soul of Star Trek. Most Star Trek stories, especially the movies have a parable that speaks about us, Humanity in some way.
If there's a point to ponder in this latest movie, I cannot even perceive it. Ebert's right that this movie is a whole lot more space opera and than science fiction.
True. But Trek can be (and has been) used to simply tell an entertaining story. What the hell was the message in "The Trouble with Tribbles" or "Shore Leave"?
I don't want Trek to become totally mindless entertainment, but the idea that it always needs to be full of pathos or relevancy to be any good is an overstatement of its first purpose -- entertain.
And, I also think Nero is yet another victim of Khan, who is still the epitome of the Trek villain. If Nero had been stronger, it may have helped give the movie the depth Ebert apparently wanted.
I wouldn't mind an aimless movie if the future of Star Trek as we knew it wasn't at stake. I am very sure this movie will be a financial success and JJ will be producing at least another Trek movie, and possibly even another Trek television series. If future Trek productions are going to be modeled on this "successful" movie, I am fearful that the soul of Star Trek would be forever corrupted. Lets pray I am wrong.
