For anyone new to either the alien or predator franchise, don't let this film conclude your verdict predecessors. Alien/s and Predator are Sci-Fi classics, and when you compare those films to this one, you can see what went wrong.
My biggest issue with the avp franchise is that it's biased towards the Predators, but that's only because I favour the alien franchise.
This film really lacks in the loveable and memorable characters the original films gave us, making each death more of a relief than a shock.
The acting wasn't bad but it equally wasn't great.
Both of the iconic monsters each have their reputation spoiled in this film.
The Predators are shown as vain dictators who only want humans to worship them, and the Aliens seem to be there just to be cannon fodder.
Why did I rate this 3 stars then?
Well, the action was goo-- decent
The special effects were err, passable?
Ok, the real reason is simply because I have a soft spot for the alien and predator franchises. This film is not a recommendation. If you want a good Sci-Fi film, check out the franchises before they were mashed into this film (you may want to give Predator 2 a miss though)
