Almost every Alien 3 draft other than Gibson's was f**ked AFAIC - and Gibson's 1st is just so-so in hindsight, a bug hunt. Ward's was visually striking and innovative but I didn't care for the story. Red's was bizarre and I seem to recall finding it interesting but weird and stupid in places - I haven't read it in years and I know he disowned it. Gibson's first I dug as an Aliens-loving kid, and today I find it fun and interesting but a bit conventional - I haven't read the second but I will be doing so soon, I hear it's good. Anyway, it's still more than I can say about the others I've read. I am curious about Twohy's, which I also have sitting on my HD to read.
The final film was a rushed, subpar pastiche of other malformed ideas IMO. They never took enough time to nail a real story that fully worked, all they cared about was making a date so they just played it cheap and rushed ahead with 'prison planet using existing construction'. For a movie of this caliber that's inexcusable.
