I've had the chance to listen, and it's good work as usual.
First, let's talk about the music. Thanks for the tip about the AVP:CM soundtrack. Sounds great! I had no idea about it. Must have missed the memo... I've always loved the original Alien soundtrack. Goldsmith knocked it out of the park, I think. The use of horns and percussion along with the contrast between the sort of romantic theme for space and the Nostromo vs the music for the creature is quite striking. Some of the sounds Goldsmith used make the soundtrack stand out among its peers. I especially like The Landing and Parker's Death. Of course, I'm one of the people who fondly remembers the original LP soundtrack and had to have the 2007 2-disk set. The soundtrack in the movie includes some of Goldsmith's work on Freud. As most probably know, Scott had the tracks slotted for temprorary use and decided to keep them in the final movie over Goldsmith's objections. And the end theme was completely replaced. The experience caused a lot of hard feelings between Goldsmith and Scott.
The soundtrack for Aliens has its moments. Some of the sound is iconic, but a lot of that soundtrack comes over from Horner's work on Star Trek. The Federation, Khan, and the Klingons all seem well represented. I like the sound of it, so it's okay with me, but I can see where there might be some complaint. It's a Horner soundtrack from the 80s. That really sort of sums it up.
The work Goldenthal did on A3 is quite good. I won't argue with people about it, but A3 does not mean as much to me as the original or even Aliens.
I suppose that leads into the liking of A3 or not. I don't love the movie. I like the Alien chase at the end and I agree the funeral scene is brilliant. I'm not bothered at all about Hicks or Newt. The Magic Egg is what it is. The real problem to me is that the prisoners are hardened criminals. The Alien becomes a dispenser of justice. If the people had been ordinary miners or maintainers, even colonists, I would feel more for their plight. As it is, the Alien is killing them, and I think "good riddance." I feel somewhat badly for the doctor, the warden, and his assistant. They're more or less ordinary people doing their best. I can feel something for that. But as audience, any sympathy for the prisoners is stripped away through the course of the film until it doesn't matter what the creature does to them. As a movie, the assembly cut holds up far better than the theatrical release because the story is more complete. But I think, visually, the image of Ripley dropping into the furnace as presented in the theatrical release, with the queen popping out, works better than in the later version.
I enjoy the AVP director cut. It does what it does and I like enough of it to watch it once in a while. I sort of like the idea of Predators watching over humanity's development better than the engineers. I don't think they could have Aliens on earth without some of them getting out, though. And all that plays havoc with the idea that the Aliens are an unknown species. But I guess we have to sort of reassess. It appears that at least a few people have known about all these things for a long time before the Nostromo lands on LV426. At least that's the subtext. And instead of doing anything sensible, people always think they can somehow profit from messing with avatars of death. FWIW, the Aliens could only be 10000 times worse than these

Predators was fun. I enjoyed it well enough.I generally agree with Ridgetop about it. Like so many of these movies, it could have been better, but that's the way it is.
