The problem(s) with A:C are not with A:C itself, but the unique heterogeneity of the "Alien" fanbase...

It's been fleshed out through a myriad of novels, novella, comics, and films and cartoons through the years since 1977.
"Marvel" fans are fairly homogenous as well: their universe is also rather well defined, and most of the stories have been already told in most of the comics and stories, and their fanbase is self-assured that when they go to a movie, the canon is established.
"DC" fans are (to a lesser degree) pretty homogeneous as well, much like the above.
Harry Potter and Lord of the Rings fans are similarly homogeneous as they have an established epic that set the tone(s) and capabilities of the whole series.
The "Alien" universe is rather unique in that, we really don't know what we are going to get from film to film or story to story. The "Canon" has been ever changing, and there has been no attempt at making its Universe into an "establishment" like the above examples have been smart enough to do. I'm afraid that Fox is a little late to the party in trying to reign it all in, but, I feel strongly that the expectations of the typical "Alien" fan is more different, person to person, than for the typical "star wars" (or X, or Y, or Z) fan, and that...THAT is the cause for most of the dischord from movie to movie. There will never be a universally acclaimed "Alien" movie due to these simple facts.
