Pleasantly surprised
Saw this yesterday, and liked it a lot. Now, the original "Predator" is one of my five fave films of all time, so I have high standards. That said, I do not consider P2, AVP or AVPR to even exist. I won't even spell their titles.
But "Predators" . . . is good. Not as good as the original, but then, neither are the sequels (and prequel) to "Raiders", but we love 'em anyway. I'll try to explain why "Predators" is good without giving spoilers.
Pros: Intense. R-rating. It's about the hunt. It's not the cartoony P's the other so-called sequels offered. The characters are an interesting group. Each one offers something both to the group and to the audience. It's good theater. There is a good deal of suspenseful buildup, interesting twists and surprises, and a lot of homage to the original. And, very little CGI. Mostly practical locations and effects. Its low budget (40 million) I take as a blessing.
Cons: I agree with those who say it ended a little early. I could have used another Act, but the lack of one doesn't hurt the film. Just leaves it open for sequels (which I hope don't take another 23 years). There's also the temptation to think "this is taking too many scenes from the original", but when watching it, bear this in mind: It's a fan-film, almost an apology for the other three so-called sequels. It's an homage to the original. Not a reboot, not a remake, but more of a "let's get this series back on track" sort of thing. In that context, the repeated use of details from the original fits in nicely. Just enjoy!
Interpretations: The title (plural predators) is BOTH an homage to "Aliens" as well as having a double-meaning, that our cast of monster chow, being all criminals, are themselves the "predators" of their own world. Minor spoiler: The Predators themselves don't get along too well either, like humans, so it's more like a free-for-all, a true "jungle" both physically and metaphorically. It's wonderful!
I, for one, will see it again, if time permits. A worthy sequel to the original, at last!
