I don't mean to offend anyone with my comment. I'm just pointing out that this whole film can be done more practically and efficiently with today's technology. The guys who do CGI are also craftsmen in their own right...and if you look at films like Star Wars Ep 1-3, you can really tell how authentic everything can look with modern computer tech. I think a lot of fans of the Alien movies don't trust CGI because they had a bad experience with the way things looked in Alien3...but that was 20 years ago and technology has come so far since then. I thin FOX should have insisted on using Industrial Light and Magic to make this film...but since they didn't, I guess we can just file this one under the long list of mistakes that FOX has made with this franchise since the 1990's.
