Therin, I saw TMP when it opened in '79 and I felt the same way. I'd been waiting for years for new Trek, and there it was on the big screen. I was right in the middle of the film, soaking up every second of it. Though it didn't quite hit the mark, it was Trek and it was new. Every time I watch the movie it takes me right back to that place.
Unfortunately, my girlfriend did not appreciate the experience and that was pretty much the end of that. Ah, well. Life goes on.
