just saw it
action factor: good, the movie is not just a dumb testosterone fest but the action develops with purpose.
suspense factor: average, but good at some parts
coolness factor: very good, excellent at some parts
cliche factor: bearable and the characters aren't so stereotyped as to be boring, but stereotyped enough to be funny in a way.
unexpected death factor: not as much as some of the other movies but still good.
--spoilers follow, but no major plot spoilers.--Main Complaint: in the dialogue, they advance the characters' awareness of what's going on, too quickly. the writers could have milked more out of the situation by realistically prolonging people's realization of this fucked up scenario. but, other parts of the dialogue are pretty good, so it's ok.
the premise as you've probably gathered from teh previews, is that they were selected, abducted, and brought to the planet (actually a moon I think). now the great thing about a plot like this is you can explain a lot of weird shit like 'why is it they could all speak english' oh because the aliens picked them out that way so they could communicate better and work as a team. it also explains why there are apparently some terran plantlife there, if the aliens have been doing this a long time they may have added plants and animals from various planets to make it more interesting.
things to look for when you see it:
I know from seeing it that there are/were Aliens (xenomorph, Aliens Trilogy type aliens) on the planet. how do I know this? there's a chestbursted corpse in one scene.
There's a new type of alien; no not the Aliens kind, and not the Predator kind, nor related to the Predator kind. It is delivered to the preserve in much the same fashion as the humans; but its plot significance is nil, so I wonder if they're establishing it for later movies. it does add to the chaotic, don't know what to expect feeling of the movie.
laurence sea kittenburne's character is awesome. I have no idea what he was eating or how he survived that long on the planet, but I suspect he had to eat other creatures/people which were delivered there to supplement his diet of strange alien fruits and shit. or who knows, maybe the predators drop in food and ammo too.
and at one point a character quotes hemingway, and yes it's a quote from hemingway, he's not oxshitting.
