I don't know anything about Roddenbury's vision. Nor do I know anything about fusion, fission, or black holes. But I do know that I spent $6 and enjoyed the heck of it. I was never a Trekkie, but thoroughly enjoyed the TV series. So, I guess if you're a purist -- don't pay to see the movie. If you want to see a light-hearted, action-packed prequel to the TV series, spend your money, buy the popcorn, sit back, and have a good time.
