1) H.R. Giger gets a thank-you nod at the top of the end credits but Dan O’Bannon doesn’t? Not fucking cool.
2) I have to assume that Jon Spaihts’ original script was filled with little things like nuanced character, and layered exposition, and biomorphic consistency, and small moments of mystery slowly building to inevitable yet surprising revelations, and then Damon Lindeloff came in and said, “Kid, let me show you how we dealt with that kind of crap on LOST…”
3) Not really a SPOILER ALERT, but: Why the holy hell was the alien mound-complex a) called a pyramid when it wasn’t in any way, and b) lifted wholesale from the Castle Harkonnen design for Jodorowsky’s Dune? Like, what?
