For whatever reason Roger Ebert loved Prometheus. In his last collection of movie reviews he gave it four stars and considered it thrilling and inventive. Now of course that doesn't mean he was right and the rest of the world was wrong - famously he was also the only critic to rave about Episode 1 and 3 and actually watch Attack of the Clones twice because he thought he might have gotten it wrong the first time. And he also gave the only positive review in history to The Happening (which he admitted was probably going to get him mocked for doing so.)

I personally thought it was a mixed bag and if I hadn't been told it was an Alien prequel I wouldn't have known any real conncetion until the final minutes. On its own merits, there's nothing that I haven't seen in a dozen other sci-fi movies/horror. As part of the Alien franchise, if you channel chased to it on cable and knew nothing about it, you could be forgiven for thinking there was nothing to do with at all. In either case, this is one of Ridley Scott's weakest features and part of a terrible creative slump he was between American Gangster and The Martian when he recovered his mojo, at least until say, House of Gucci.
