You can make a list of about 20 things that could have been different about the movie that would've made it an amazing film. That said, those 20 things weren't changed, and as it is, it's pretty atrocious.
One change would be that this music should've been played throughout the whole movie.
Prometheus was better than Alien Resurrection, and the Alien vs Predator movies. That doesn't make it good, but it was a little refreshing to get something in this franchise that wasn't complete garbage.
Five for the music too, it's the band Evidence, with The Evidence! I haven't heard that for a while but it was played on the Disco To Go radio show here in Pittsburgh by Rick Jankowski.
Pretty much what I was thinking, fuck Prometheus. Giger along with Syd Mead essentially carved a hole in my brain with their designs and concepts. Hopefully his casket is as phallic as possible, RIP.
