Prometheus is a fascinating mess of a movie. The script in nonsensical and the editing is even worse, but visually it is unparalleled and I'm very intrigued by the ideas it presents (even if they thematically contradict the intention of the original film). Covenant, in my opinion, improved on Prometheus by getting even weirder with the material, and actually competently putting the movie together. Where Prometheus played things safer, Covenant went wild, detached itself from any pre-conceived notions people might have held about the franchise, and told a story that explored some concepts that I find really exciting.
I'm all for this being eight or so hours of an unhinged Ridley throwing his ideas at the screen. I just hope that, if there is a season two, Ridley actually remains involved and directs a couple more episodes. I know he's a busy man with a hundred projects up his sleeve and would never stick around to be a proper showrunner, but him directing a few more episodes if this is a hit would be very exciting. If this does get a second season, I also wouldn't be shocked if the budget is expanded on from this first one; remember, this first season wasn't actually made for HBO Max. This was a TNT show, so basic cable.
