I never want to sympathize with the Alien. If we ever get to that point in the films, the horror these creatures stir within my mind would be rendered null. Resurrection almost went there with the Newborn but pulled back just as fast.
I absolutely appreciate the callback to original ideas by O'Bannon but I do think that Ridley relocating the ideas of a society with art and architecture to the Engineers was the better move. While it expands on old ideas being brought back and showcased within new films, it also keeps the scary, unknowable horror of the Alien.
I would, however, love to see Blomkamp's script realized through an audio drama, comic, or novelization!
