AvP:R (the R isn't really for Requiem, it's to make sure you suckers know that it's rated R) was directed by the Brothers Strause (in their feature debut) and written by Shane Salerno (Armageddon, Shaft).
I love the Alien movies, though I'm far from being an expert. I love them, love them, love them. All of them, even Alien3 (so long as it's David Fincher's work print version, not the Fox executives' version) and while there may be a few issues with Alien: Resurrection, I love it, too. Predator...well...I found them to be interesting, but not "omigod PREDATORS R SEW COOL!" interesting. The Alien aliens win for me.
I hated the first Alien versus Predator movie. Hated it. Paul W.S. Anderson's shoddy treatment of both properties, and essential transplant of the two species into the Resident Evil script, really frustrated me, though the Predalien hybrid introduced at the end of the flick was really interesting.
AvP:R makes the first one look like a masterpiece of Shakespearian proportions.
The film starts out with the biggest mistake EVER which was carried over from the first flick. Can you tell me, honestly tell me, that the Predators would actually carry their impregnated homie back onto the ship without any sort of protection? They have a super-special Alien tracking sight thingie in their masks, for the love of Pete. They'd KNOW that their fellow Predator was carrying a really nasty hybrid and would DISPOSE OF HIM / HER IMMEDIATELY. And by really nasty, I mean to say that the Predalien was a Queen / Uber-Facehugger unless forcefeeding multiple embryos down their host's throat is how the Predators procreate...
AND WHERE DID THEY GET THE FACEHUGGERS THAT ARE ON THE SHIP IN THE BEGINNING?! They couldn't have rescued them from the temple, there wasn't enough time to bottle the six (or whatever) of them up so nicely before the building went bye-byes.
The Predator knives (the ones that come out of their little gauntlet things): are they some special acid-resistant metal or something? Even their armour isn't acid blood resistant, but their weapons are, by golly...
There were very few, very VERY few, things in the script that were surprising and even fewer things that weren't slightly misogynistic or racist. Only white people live, only the menfolk (and the half-assed Ripley stand-in) get to shoot the guns, and only men get to be impregnated by facehuggers while already pregnant women get to be impregnated by the Predalien Queen. This is one terribly written movie. And, may I mention how much I hate that the lead male character is named Dallas?
Shots and even whole moments were stolen (even repeated once or twice) from the various Alien films (maybe Predator, too...I don't know,) but usually Aliens and Alien3. It was nice the first couple of times, but when conservatively 66 of your 86 minute runtime consists of stolen shots and moments, it gets boring fast especially when it doesn't feel as though the shots were understood by the filmmakers beyond "Oh, yeah! That was an awesome moment...let's do that!"
There are two really good things about this film, though: Alec Gillis and Tom Woodruff, Jr. came back for the effects (their Alien work is phenomenal) and the score by Brian Tyler took all kinds of cues from the Alien and Aliens scores (again, probably the Predator stuff, too, I don't know) and melded them into something that really worked for this film, though it did feel a little uneven, going more for the military feel of Aliens and I imagine the bombastic Predator.
My biggest problem with these movies is ALIENS ON EARTH BEFORE RIPLEY LEAVES IT?! WHAT?!?! Maybe it's explained in the comic books or one of the games or something, but you can't tell me that none of the characters in the first Alien film had ever heard of the complete nuclear annihilation of even a small town because of alien infestation ESPECIALLY when there were four survivours. If Weyland-Yutani were so gung-ho about finding these things (including the Predators?) separately or together, they would have LONG before the Nostromo was even drawn on paper.
The new breed of "versus" movies have the same problems: the crew aren't paying attention. If explanations to any of my concerns are in the comic books, they really need to be in the movies for them to make sense IN THE MOVIE.
Frustrating and disappointing.
