I found Skyfall to be an uncomfortable mix of classic Bond over-the-topness, and Bourneish/Nolanish 'realism'.

Either Bond is superman, or he gets old and has to retire. Can't have it both ways.

If you head into a gun fight with 30 year old intel on where the guns are- don't be surprised if someone moved them while you were out.

Fix that (if you can) and maybe I will have some use for Skyfall. As it is now, it's too silly to be serious and too serious to be fun.

(And maybe add a post credits scene of Kevin from Home Alone waking up and it was all a dream. If you keep the Home Alone action at the end, that is... which it sounds like you're not.)
