I saw the movie today in Poland in the Pre premier screening.
The script is awful. The movie is very shallow with it's two dimensional characters. It mostly feels like you're watching a sitcom, or a bad slasher movie. With all it's cheesy aspects.
The Predator is a God here, no mere Alien can scratch his butt, he only gets face slaped (literally) a few times and tail whipped. He takes Aliens by numbers, catches them by the throaths and headshots them with plasma cannon in "bad breath" range without getting acid splash all over his tuxedo. He is somewhat very stupid, getting on a suicide mission where the odds are 1 to 100, guess nobody likes him in his clan or something. He has all the special "Alien vision" sights but he is so bad ass that he can't even look up once and the Aliens always sneak up on him with the face slapping and all that.
The aliens? Cannon fodder I'm Afraid, even in the crappy AvP they got more attention...
The whole teenager problems with girls and guys bullying other guys is just out of place. There are many cheesy dialogs which are just plain dumb. There is humour mixed up in the plot and it isn't convincing... not in a situation like this.
There are many stupid scenes, where there is no logic at all. Spoiler:
The ship is hit by the Plasma caster from the inside. It changed it's course and is crash landing on earth. Ok... if the ships hull was compromised then why nothing burned inside? The ship crash landed like a swan on a lake, with grace to be exact. No crater, the ship is practically undamaged and didn't melt at all (ok it's made of high resistant metal, but then why didn't it burn from the inside because of the hole the plasma caster made? It should fall apart easilly).
End of spoiler:
The camera seems too shaky in many places, the action shot of humans shooting "something" and you really don't know what. The movie is really chopped up, there are many scene transitions and you seem to be scratching your head in many situations. It's like a bunny hops all around the city of Gunnison.
The end is the crappiest of them all. The Predator is such a bad ass that he fights with his bare hands, even crushes one of the aliens head with his boot.
Don't want to spoiler you too much, but really it gets crappier with every minute.
