Watched it last night, this time the thing that really bothered me was how quickly things went around after the lights go out. From a scene to another the city is implied to be already under aliens control, but so far Chet haven't reached the hospital, establishing a hive and making all those multiple bellybursters. Yet somehow there are enough aliens to kill the national guard as well as a shitload of citizens, as people were already thinking about evacuating the town despite that at this time there can't be more than 3 aliens besides Chet.
Feels like there are 30 minutes missing there. If the scenes with Chet at the hospital were placed earlier, maybe it could work a little better, since those extra aliens would come from there, and in the way things are, those bellybursters must have grown really fast, considering the amount of adult aliens we see at that last hospital sequence. So despite that at the start the facehuggers take a little longer to impregnate, after that Chet pulls a AVP and its done. Hmm... maybe fanedit can make some difference.
The speeded up life cycle also bothered me on AVP, as well as how fast the hive and the eggs spread across the pyramid, but on AVPR the aliens simply increase their numbers without explanation, unless Chet found other pregnant woman on the way to the hospital offscreen.
