Although I liked the special effects in the first movie, they were probably not the point; fans of the TV series wanted to see their favorite characters again, and Trek II understood that desire and acted on it.
Here comes a sequel that's worth its salt. The second Star Trek movie is swift, droll and adventurous, not to mention appealingly gadget-happy. It's everything the first one should have been and wasn't.
Star Trek II: The Wrath of Khan is a movie that transcends it's genre, it's format, it's fan base to really get inside the hearts and heads of people across all barriers the world over. This is the way to make Star Trek movies RIGHT.
