AVP was very disconnected from it's roots in my opinion, the predators in particular, seemed like totally different creatures from the preds from the first 2 movies. It really felt (to me anyway) like both creatures had been transformed from ledgendary. iconic characters, into generic beasts that didn't really define themselves as aliens & predators & rather, seem almost like different creatures inow what I mean. The film just didn't have that special something that defined it as being an alien/predator movie.
Enough about AVP though. I agree with u guys about Fincher not being given enough credit for A3, admittedly, the first two movies were better, but A3 introduced a gothical, creepy atmosphere into the series which had not been present in any of the other films. Fincher would be a good candidate for the next alien/pred movie or the next AVP
