That DOES make it even creepier. I'm watching TT right now (watching each EE once for entertainment, ove with commentary in the next two weeks) and I think it will be really neat to see Gollum go from a scary, almost "monster" in The Hobbit to a sympathetic character in TT who wants to free himself of his inner demons. And then become a psychopath all over again with RotK. I won't be the tool to say "the whole series has really been about Gollum!" but it will be neat to have a character who really develops across 2 trilogies, alongside Bilbo and Gandalf.
