Just read this over at fileheaven and thought i'd cross post:
Wow, that's some great analysis! i honestly never thought of some of the ideas and shows what I often forget, some director's really do think about their content and its not so much 'luck' creating successful films, there is a high level of skill and analysis required.
Although I don't agree with him on Alien 3... Alien 3 was much braver than Prometheus. There were more risks taken, and although relying on Ripley was not entirely necessary, it did not overly hinder the movie. However it is a passing comment he makes and isn't allowed to justify that opinion.
