James Bond movies are like coffee. Everyone thinks they are an expert on the matter.
Also, they are like coffee in that while I don't consume them frequently, I enjoy the taste enough to consume one now and then, mostly in the name of being social.
They can also be likened to coffee in that by consuming it I feel like a super spy and can perform amazing athletic feats that I would never have attempted prior to consuming.
They are again just like coffee, in that I know I should shut up when the "experts" start talking about what actually constitutes a quality experience.
So if you are a Bond expert, you should not take my opinion into account when making any movie ticket purchasing decisions. If you like a good Bond-esque film from time to time, Skyfall will entertain you thoroughly.
