*** minor psuedo-spoilers ahead ***
It really felt to me more like a generic action film than a "Bond" film, although a large-scale sequence at the end reminded me of some of the "bad guy's lair" stuff we used to see in the later Connery and most of the Moore Bond films.
I like that the "rebooted" Bond has less gadgetry this time around, but "Quantum" took too much of that out. The newer films show more technology back at HQ... in the older ones (with the exception of Q's lab), it seems like most of the high-tech stuff was out in the field with Bond.
The world-wide "Quantum" plot is not entirely bad - it gives Bond a shadowy organization to find, root out, and eliminate, rather than resurrecting the Cold War or turning him loose against drug lords or terrorists. On the other hand, it seems as if these people are motivated by money, not ideology. Following the money flows, interrogating suspects and chasing the resulting leads seem like the way to dismantle this sort of worldwide enterprise - is Bond the right sort of person to do this work, rather than the FBI, CIA and Interpol?
