Your comments on Skyfall totally echo mine. I came away feeling utterly underwhelmed. Yes, it's an improvement on Quantum of Solace - seeing as that one is almost everyone's least of the whole franchise it HAD to be. Anything less and the death knell would certainly be sounding right now. Yes, the pre-credits sequence is great but as soon as Adele started squawking I began to find more fault than favour.
To be brief (I would be here all day otherwise) my biggest complaint is that Skyfall felt grubby and depressing when what I want in a Bond is glamour and fun.
