I honestly have watched 'Aliens' well over 300X...easily. There was a point back in the day where me and my buddies would watch it daily...sometimes mulitple times a day. And we weren't even on drugs
I was on a local talk show a little over a year ago where they invite guests in who have particular areas they are 'experts' in. I told them mine was the movie 'Aliens' and that no one could 'stump' me with any questions or trivia about it. I fielded about a dozen questions or so over the 10 minute segment and wasn't stumped once. Stuff like "What was Newts real name....what was the name of the cat found with Ripley.....what was written on Vasquez's gun....things like that.
So I have to ask: Do some of the things they did in the subsequent films absolutely drive you insane? I'm not nearly the fanatic you seem to be, but the later films (A3, A4, AVP, AVPII) drive me up a wall. They spend so much time creating such deep and consistent lore in the first two films, but then began to take liberties (that, IMO, are inexcusable) in the latter films.
In A3, we get facehuggers on the Sulaco and the escape pod. Uh...really? How exactly is that possible given the events in Aliens? If you ignore that, it's actually a decent movie. But that very premise drives me nuts.
A4: Inferior to its predecessors, but I guess you can excuse the liberties they too in changing cannon since they are all probably explainable just by the fact that they were genetically engineering xenomorphs, so variations in behavior and biology would be expected I suppose.
AVP: You know, actually, the downsides of this moving have nothing to do with continuity. I think they actually did a pretty good job of preserving continuity here. They appear to have taken some liberties in terms of how fast the xenomorphs mature, which is a bit of an annoyance. But it wasn't a major flaw. Or maybe it was, but it was so overshadowed by other silliness that it just feels like it didn't matter.
AVP2(Requiem): This is where they went off the deep end in changing at least 2 (if not more) fundamental pillars of Alien cannon: (1) Continuity in terms of xenomorphs being in a populated area, and survivors living to tell the tale, which would make it HIGHLY unlikely that the crew of the Nostromo and the marines on the Sulaco would have had no clue. Yeah, they tried to invoke the conspiracy/"government cover up" theme to imply that the truth was buried, but that didn't ring true to me at all. It was just too shallow to allow me to suspend disbelief. (2) The alien biology in terms of how they reproduce and develop was completely thrown out the window. This film could have been amazing, and they blew it.
Anyway, yeah, it just makes me mad to see how the franchise was ruined. I imagine a lot of the more fanatical fans must have been even more annoyed.
