Haven't watched either of the OSS 117 movies yet but another very good and very funny French spy comedy is the tv series A Very Secret Service, which also set in the 60s and mines a lot of first rate comedy gold out of the changes in attitude between that era and our present-day.
And possibly the very best spy drama I've ever seen is another French series called The Bureau, which I can't recommend highly enough to anyone at all interested in the genre or just in great tv, period.
The Skyfall one's pretty good, from what I remember of the movie. Some of it (like the train thing) would apply to almost any Bond or over the top action movie in general, but the more specific stuff was well done.
Started to watch the Spectre video but then thought, no, if I ever do see the actual movie I'd like to give it an honest chance, which for me means trying to go into it with as little foreknowledge as possible in this day and age.
