Saw it at the weekend. It's not overly good but I went in with low expectations so didn't really mind it. The lasting impression of it is that it didn't need to be a Predator movie, and tbh while I know the intention was for it to spawn sequels and re-start the franchise, I honestly don't think it'll happen. Not off the back of this movie, and that means probably never.
Is Predators better? Well, I thought Preds was basically fan-fiction on film, while The Predator isn't. But it's a close-run thing. Very close. My gf actually said she thought the first AvP was better.
I think a review I read had it spot-on, by comparison with the original Predator: "I doubt anyone will be talking about this film in 31 years' time, or even remember it."
I think part of the reason the original was considered so good was the work of the actor playing the Predator,Kevin Peter Hall...Kevin Peter Hall - Wikipedia
Nothing cgi about Mr Hall,he was tall big and ugly in that part..when he finally tracks down Arnold,and begins dropping his gear,stops,issues that godawful roar and spreads his wingspan with the claw tipped hands,you figure even Arnold has bitten off more than he can chew.. read the wiki on him,didn't realize he was the mutant bear in Prophecy and was on Harry and the Hendersons too..
