Yeah I spent my childhood listening to the motion picture soundtrack(It is still my favorite movie soundtrack of all time)for years before I saw the movie and I kept imagining what kind of epic adventure the movie was set too, needless to say when i finally saw the movie on VHS it was a huge letdown. They didn't really go anywhere, it took forever to get anything done, and Spock and McCoy didn't even argue and that was my favorite part of TOS when I was a kid.
Thankfully I saw VH Followed by WOK a few weeks later and that redeemed the movies for me.
I still watch TMP from time to time because it isn't a bad movie but I can see how after ten years of waiting it was a letdown for fans. I mean it was slow paced and it just retold the same story as an episode of the series. I have a feeling if I had seen it in theaters I would have wanted my $5 back.
