So what we have is 1. expectation....for years many fans have 'expected' that the Space Jockeys are actually creatures. 2. Ridley returns and does something unexpected...the SJs are actually humanoid. I like the second option because I don't want what I've always expected, I want something hat turns expectations on their heads a bit so that when I'm returned to a familiar world it won't be a series of 'oh, yeah, I thought so' as opposed to a 'omg, what the fu€k is going on?'
