I was really pumped up in part because the movie reportedly wasn't very "Star Trek-like" in the sense that the director wasn't a Star Trek fan and reinvigorated the movie with an outsider's take. I used to be a Trek fan, but have gotten grossly disenchanted because, aside from the original show, the characters are so stiff, stuffy, and BORING! I wanted to see a fresh, new take on it all.
In truth, it was more Star Trekish and truer to the "Original Show" and cast than any show or movie featuring the Next Gen cast and onwards. It was very lighthearted, humorous, and the casting was good... everyone portraying their counterparts without being extreme caricatures of the originals. I was especially worried that I would only see Spock as Sylar, but Zachary Quinto did an awesome job. In fact, I felt he pulled off a better job of being "half-human" than Nimoy ever did.
