I like the tone they're sticking here. Preserving some level of the deathly serious scifi from the original, but leaning into some level of self-awareness and fun. Destiny is not Halo, and it's not going to be. The lore is bland, and chronically uninteresting. Bungie is better off highlighting what people do like about their world, rather than trying to make the flawed elements more popular.
All that said, the path of 'CG teaser for CG teaser promising gameplay footage in six weeks' is pretty annoying.
