I agree that it seems odd somebody would go to this much trouble for something this obscure, but then again there was that fake 'Orson Welles' MOONRAKER with Dirk Bogarde' site that felt so weirdly right.
I'd built it up in my head so much that nothing could have measured up expectation-wise, but it isn't bad. I actually like a lot of the LTK score, especially the Bond-as-badass parts, like when he demolishes the camera on Sentinel.
