Skyfall was very enjoyable, had many good moments, and did well a lot of things Bond films don't always do, although I felt it missed some opportunities and dragged a bit by the end.
I've recently seen several people saying that Skyfall and Windows 8 were surprisingly good. I am shocked, I just assumed that both were a necessary transition period, but if there was something good there, it would only come out in a follow-up. It seems practically a law of nature that new versions of windows need an edition to get the teething troubles out of the way.
