I agree wholeheartedly.Bond movies are time capsules. They capture the mood and attitudes of each decade. In twenty years, we will watch Quantum of Solance and say "Why so serious?" The U.S. and U.K. were involved in wars. The economy was tanking. Et cetera, ad naseum.
And for this reason why Moonraker was a smash hit at the time of its release, and why in following years it was derided, and in future years it will no doubt be revisited and once again find favour when the next relevant time capsule comes around to embrace it.
(Which will probably be when we are asking ourselves why QoS was so serious)
