Well, if there is one thing you can't question Scott achieved with his two prequels, it was bringing A-list class back to the Alien series. I don't only mean that in the sense that the people in front of and behind the camera are top class, but the hype and prestige in the build ups and premieres of both movies was exactly what Alien deserves. I enjoyed that.
The AvP movies were particularly dark years as a fan in a movies sense. At least they're a distant memory and the calibre of filmmakers we want to see tackle the next film is of a significantly higher standard. I thought we were in trouble there after Requiem in 2007/8
