7. Star Trek: Enterprise - Trip Tucker
It's no secret that "Enterprise" wasn't the favorite of a lot of Star Trek fans. To me, however, the characters were always well-thought out. In Tucker's case, he filled the role of the engineer who had rash ideas, and was often the other side of the "coin" when it came to his reasoning and T'Pol's Vulcan ideology. Considering those two were in a relationship briefly, it gives credence to the idea that opposites attract. Plus, like every member of any Star Trek show, he was involved in a lot of crazy adventures, one of which had him be the first human male to become pregnant. Weird stuff, even for Star Trek. Which is why his death in the series finale didn't seem to make any sense. The finale, taking ten years after the previous episode, has the Enterprise crew carry out one last mission together to save the daughter of an alien ally. They manage to rescue her, but at the last minute are attacked by the kidnappers, who had sneaked aboard the Enterprise. Tucker, pretending to help the kidnappers, overloads two conduits and is fatally wounded in the explosion. That's how the series ended. Myself, the fans, critics, and even the actor who played Tucker felt that his death was forced and unnecessary. Tucker had been in worse situations before and unnecessary. To me, this move was just to get the audience shocked, and it did not work at all. It's no consolation to hear that had the show come back for a fifth season, Tucker would have been revealed to be alive. Well guess what, writers? The show didn't come back, and you killed off one of the few good things of your show. That's a hell of a way to end 18 years of Star Trek television history.
