I am a big sci-fi fan, but I have never gotten into Star Trek. I have seen only one movie, I think it was Insurrection, but didn't understand it because it seemed to be part two of a story that happened in another Star Trek movie. When I saw the teaser for Nemesis, it looked like something I would enjoy. My question is:

Do I have to watch all the other Star Trek films in order to understand Nemesis?
