Who made this film anyway?

I'm finding it very interesting reading the boards now having seen the film as opposed to before when we were all just expecting it. My thoughts are that opinions are like assholes. We all have one! But seriously. Ridley Scott made the film and he made the decisions that made it what it is, not us. If all the theories we had were in it, it would be ABOMINABLE. Yes some of it doesn't work, but there were bits of Alien I found boring that others might find amazing and vice versa. What I came away with this evening was that Alien worked by accident. If anything Prometheus fails because it has been overthought. (As evidence of wrong footing, would we like Alien if it had included RS original idea of the alien biting Ripley's head off at the end and recording the last log in her voice? He's not right ALL the time). But until we all complete long careers as multi-million dollar box office smash directors, I think we should remember it was his film to make - and I think he'll do rather nicely out of it too.
