Looks like the only people inspired enough to comment on this movie are the people who love it, so I guess I'll be the voice of dissent-- I watched this for the first time after seeing the entire Alien series, as a way to prep for Alien vs Predator. I didn't expect much, especially after seeing the trailer, but I was surprised by how BORING this film is. The characters are completely two dimensional caricatures/stereotypes with no development whatsoever, the plot drags along, the only "action" is lots of shooting and marching around in the jungle, and the Predator doesn't even show up until an hour into the film. The lines are cliché and there isn't an ounce of tension or investment into the characters--by the time the first twenty minutes were over, I was actually waiting (eagerly) for them to be killed.
If you're into clichés, this movie is for you. If you'd prefer something with a bit more depth, stick with Alien (the original, NOT the sequel).
