As a writer I cannot say anything bad about James Cameron because the man knows how to tell a story. "But Pike his stories are generic and boring hurrr" Yes but I have never seen anyone take so-called "generic tropes" and build them up so well. Watching a James Cameron movie is like watching someone draw a perfect circle. Circles have been around for billions of years and these days are not exactly artistically groundbreaking or interesting on an aesthetic level but the fact that some people can just whip a perfect one up freehand is a marvel in and of itself.
I don't expect anyone here to agree with me butWhen it comes to storytelling I am an "architect" first and foremost and I am more interested in the building process than the finished result.
As an aside I can hardly remember any of the cast from the first film but I do fondly remember the cast from the second! (This is not to bash "Alien" in anyway; I'm just not seeing the "better characters" argument)
