So unless I overlooked something, no one posted
this yet. Short version: many/most of the complaints about the film were addressed in the original scriptment. Which was unfilmably long. On a related note, the initial cut was four hours and eighteen minutes long.
Me, I loved the thing. Yeah, it had problems. I didn't care. Like, at all. As a point of comparison, I'd argue it's no more dumb than The Dark Knight was. Or Star Wars. Or various other works of fiction beloved by geekdom.
Also, the antagonist was Duke Nukem. How can you not love Evil!Duke Nukem?
I wonder how you could make a sequal to that... Mabye another story set in the same universe, but not a continuation of the first.
A producer (think it was a producer, anyway) suggested that we'd seen everything there was to see on Pandora's surface, but that the underground hadn't been explored yet. Which could potentially offer a way out of the "nuke the site from orbit" trap. OTOH, Cameron's mentioned that the sequel wouldn't necessarily even take place on Pandora, so who the hell knows wtf is going on?
Oh hey, coolest--and cruelest, because it probably ain't gonna happen--rumor about Cameron's plans; xenomorphs in 3D, Scott+Cameron=love
