re: Movies with really good ideas as the basis, that didn't work in reality

I think I'd put Prometheus in that list. I was really intrigued with the idea of the movie. It was also beautifully shot but most of the characters just sucked. From the "scientist" who takes his helmet off right after landing on an alien planet to the geologist who gets lost even after mapping everything out with high tech equipment. Those things kinda spoiled it for me. Plus I had such high expectations for that film..
