I thought Prometheus was pretty solid
a movie that just didn't quite stick the landing
Always been a sucker for this franchise, the original was ahead of its time and I think had a much greater influence on modern filmmaking than it's often credited for. The next two movies were quality as well, and I enjoyed that they all had a very different feel despite basically being about the same thing. After those 3 however, well yeah mixed bag at best.
First impression is that I like that it looks like they've gone back to a spaceship for the setting. Might be a little old hat for claustrophobic tension building aliens attack space horror but familiarity isn't always a bad thing if the other parts are executed well.
