I like the Alien 3 we got in a lot of ways... But after having read the second draft of Gibson's script, I felt rather bummed. I think that would have been the overall best script to go with. It would have touched on the last conventional plot line available - the company getting their hands on the Alien. The only other idea that would have really been satisfying would have been the Alien Homeworld idea, but I somehow doubt that was ever seriously considered for reasons of budget... Though I just imagine an entire Giger-planet with aliens all over it and can't help but think that something like "The Lost World" with Giger/Winston creature designs would have been such a compelling high note for the series to end on.
