Missing one thing:

Rating: Null/10 (17 November 2002)

Intrigue. In Alien, the characters don't know what they're getting into and the only reason the audience knows is because 1. The trailers, 2. the Title and 3. by now everyone knows the reputation of the film . . . and it was good. In Aliens the characters know the creature, and declare war neglecting to calculate the possible numbers they face . . . and it was good. In Alien 3 we get a prison. "But they're not prepared! That's the intrigue," you say to which I would answer, "If they were prepared there *couldn't* be a film. They'd take out the Alien in 10 minutes."
Alien 3 just cannot compete with its predecessors. The film is 'okay' and it's up against two of the most influential sci-fi horror films by Ridley Scott (the director with the slickest style) and James Cameran (one of the best action directors) scores composed by the legendary Goldsmith and Horner. . . Alien 3 has David Fincher and Elliot Goldenthal. Fincher is a good director, but outclassed by Scott & Cameran; Goldenthall has yet to impress me with one of his scores, and has yet to not annoy me with one of his "sequel" scores (Batman Forever & Batman & Robin come to mind).
The uninteresting premise of the film, the uninteresting setting, uninteresting characters, uninteresting story in the end just kill the film.
More effort seemed to go into shaving Weaver's head than making the script good. And, I'm sorry, but the handful of well crafted scenes where Ripley is emotionally torn, or faces a difficult decision--the whole 3 scenes in the film what have a valid 'deeper meaning' does not save the 90% of the film that is boring and stale.
Many people found the jump from Aliens to Alien 3, the return to one alien and the fate of the survivors from Aliens unforgivable. I'm somewhat torn--I don't mind such things happening if the new route is good. The route chosen for Alien 3 was mediocre, and so the break from its predecessors did come across more disappointing. Change is not always good; change for the sake of change is typically bad. Alien 3 is a good example of this.
In the end, all of the elements of the film are mediocre to good with the exception of the script which did not live up to standards. Hence, the film is overall just "okay." But after the caliber of its predecessors, Alien 3 really is a disappointment in terms of quality.
