Cool but bad, and can someone debunk my observation?

Rating: Null/10 (14 August 2004)

The movie was cool and the effects were pretty good (preds couldve been a little more menacing), but everything happened way too fast. From gestation to deaths to fights to 'plot' advancement (whats this? oh **** get out! OK phew). It was all too hurried to be anything near the epic clash it should have been. Little and meaningless character development, and too much focus on pointless crap. Many things were just not believable. Seriously, why do people let scenes through in which a 'scientist' enters a room and upon a brief glance at some symbols, has assimilated the dialect and has an in-depth synopsis ready for recital?
Also, correct me if I'm wrong, or I at least missed something, but consider the following: 1. Alien and Aliens both dealt with the Weyland Corporation, 'The Company'. Ripley blew up their ship in 1 and Burke was pissed about it in 2. 2. Ripley was in stasis for 57 years between Alien and Aliens. 3. The real Weyland, model for the line of androids which Bishop belonged to, appeared in the end of Alien 3, knowing all about the species and wishing to get a specimen (just like Burke in 2). As far as I remember, he didn't die in 3.
(some obvious spoilers ahead)
So then, if in AVP, this is THE Mr. Weyland, why doesn't he recognize the facehugger/xeno sculptures on the walls? Or the telltale burst chests? Why doesn't he recognize the xeno when its right in front of him? This would lead us to believe it took place before the Alien series... except it obviously Didn't, since he DIED. Plus, if Weyland Corp was made well-prior to Alien, and was still around in Aliens, and this guy is THE Weyland (presumably the founder), its hard to imagine he would still be alive. The exact timelines aren't given, but youd have to stretch to make any sense of it. Don't give me any cloning or next-of-kin bs, the way it was presented just didn't make sense. Why is that?
