Prometheus is a movie filled with adults, professionals (scientists even!) that just run around the whole time behaving like teenagers in a slasher flick. It was boring, formulaic, and filled with uninteresting characters that I couldn't have cared less about. My biggest problem with the movie though, is that like Predators from a couple of years ago, I feel as though Prometheus is ultimately just doing a very poor impersonation of a much,
much better movie.
Having said that... maybe it was the handful of decent scenes in the movie, maybe it was the interesting concepts they were playing with, or
maybe it's just that it has ties (tenuous as they may be) to other movies that I really love and care about, but I
did enjoy the movie to a certain degree.
Played out as the "ancient aliens" idea is, I'm a sucker for it, and I like that's the direction they went with the Engineers. I loved the mystique of the Engineers, and I hope they get explored further if any sequels are made. The pregnancy scene was great. It was the one genuinely tense part of the movie. Though the squid baby looked fake (and stupid) as hell. So yeah, it wasn't a total stinker and while I understand people (myself included) were disappointed with it, I really don't see a reason for it to receive the kind of it has.
Overall, I found Prometheus to be an exceedingly dull and oftentimes sloppy movie that I somehow managed to enjoy despite itself. I have the suspicion that a stronger movie (even if only slightly) exists somewhere on the cutting room floor, so I look forward to checking out a potential extended cut.
