As a rule, geeks are grumpy.
Sure, they follow their particular favorite movie / TV show / comic book with slavish devotion, but their future experiences with said favorite thing are colored by the "newness" of the first time.

James Cameron avoided the dreaded and feared geek backlash by making a completely different movie in 'Aliens' than Ridley Scott did in 'Alien.' (Of course, I can imagine the reaction in pre-production if the movie were released in the time of the Web: "Cameron's just a low-budget hack. 'The Terminator' was cheesy, and he'd be better off sticking to that low-grade horror genre, rather than screwing up the greatness of Scott's claustrophobic vision!") Every film since then has been either poorly written (Alien3), or poorly directed (Alien: Resurrection), or both (Alien vs Predator). At least you could point to the pedigree of the two direct sequels -- David Fincher, Jean Jeunet, Joss Whedon. With 'AvP,' you has Paul W.S. Anderson. [shudder]
And here's the real kick in the crotch: 'AvP' KILLED at the box office, bringing in $171 million worldwide. So, being the money-grubbing whores Fox is, they're denying us a real return to the 'Alien' realm we've been craving, and instead, giving us more pap with 'AvP2.'
Two things give me hope about this flick:
It's not written by Paul W.S. Anderson.
It's not directed by Paul W.S. Anderson.
