I don't believe Alien 3 is one of the worst movies ever made. However, I do believe it is one of the most disappointing. One of the most difficult parts of story telling is creating characters you give a damn about. If you have no feelings for a character, you could care less what happens to her/him. Alien 3, in the blink of an eye, managed to kill off not 1 but 2 characters everyone gave a damn about - Newt and Hicks. That's one of the biggest missteps in movie history. Just as well, Alien 3 managed to take any sense of fright away from the creature.
Featuring more aliens that aren't the slightest bit frightening, a completely lost Winnoa Ryder, and of a large muppet creature covered in mustard and cheese, Resurrection isn't very good either.
