So now then, Star Trek.
I never saw Insurrection, and I can't compare Generations because of the William Shatner handicap, but I didn't enjoy Nemesis quite as much as I did First Contact. It reminded me of the fact that despite liking the show, the only regular character I really ever liked was Picard. I guess he makes up for a lot. Still, it was a fun little movie.
The make-up design was brilliant, and despite some very contrived moments in the plot, there were plenty of sweet spots to make up for them. One of the problems inherent in making a series of movies off of a tv series is that there is so much back story and subtext that the majority of the audience already knows, but still must somehow be conveyed to the first-timers in the crowd. As someone familiar with the backstory it is hard to say, but I think there were some important elements that were left unexplained to the uninitiated.
I'm really trying to leave out spoilers here. I am not a big fan of reviews that give away major sections of the plot. I was tempted to do two reviews, and give a spoiler warning on the second, but I don't see much point at the moment. In short, Star Trek: Nemesis is a good film for Trek afficianados, a good film to see on the big screen, and a good film to see as a matinee.
