After seeing what happened to Ridley Scott's _Prometheus_ I have become very cynical about Hollywood's ability to do anything
right. Clearly they can get sequels right every now and then, I think Avengers was better than most of the other Marvel movies, and I think the latest Spiderman was better than the first one.
But I think Hollywood does much better with new ideas than it does with sequels to blockbusters. I think the need to produce a marketable sequel to a blockbuster supersedes the desire to produce an actual engaging story.
