Well I for one thought that script was horrible.
Honestly was that the best Alien prequel anyone could come up with? What a load of rubbish really, I'm glad they changed it, but I can't help they would have been better off scrapping the whole thing and starting again.
Yes there were cool moments, the med pod scene I particularly liked, being fixed up after a chest burst, nasty... good job there was a gun next to the pod to dispose of the Xeno. Yep that sucked.
The whole ending with the ultramorph (honestly, you called it an ULTRAMORPH!) being a giant pussy... well I guess it's comparable with cuddles for crapness.
It makes a lot more sense why Ridley did what he did now, I just wish he had actually taken the time to make an excellent film rather than a decent one (at best).
I sincerely hope they can do something good with P2, I mean the engineers have 2000 years of evolution on top of what we saw in the film, they can practically do whatever they want.
