I am one of the few who actually really liked Prometheus a lot, even knowing nothing can compare with Alien and Aliens, I still considered it a return to form over Alien 3 and Resurrection. (And let's take Scott's cue and pretend the AvPs didn't happen.) Having said that, I enjoyed Covenant overall, but I was disappointed in it both as a followup to Prometheus and a prequel to Alien proper. Still better than 3 and Resurrection, but the whole David plot line just was nonsensical to me. And I also had something else recent to compare it to: the amazing Alien Isolation game. Now THAT lives up to the originals. I feel that Scott needs to let fresh blood take on the franchise, but with his blessing/oversight (someone who isn't Paul W.S. Anderson, who made a few great movies but turned into a weird combination of Uwe Boll and Michael Bay with AvP and Resident Evil).
