Time has really flown by. It really doesn't feel like that long ago since I watched Skyfall (the previous Bond film). One of the things about growing older; our perception of time is faster than back in childhood, a time filled with nostalgia, where every experience was so much richer and deeper than if we did it today.
SPECTRE is built on nostalgia. The eponymous organisation is not a new invention but rather a re-introduction of the old from Sean Connery's days. It tries to create a coherent universe with the other films since the Casino Royale reboot, and in most cases it's successful. The films is very wonderfully shot and drips with atmosphere.
However, there is a limit to how much you can exploit people's nostalgia. This instalment doesn't add much to the Bond franchise, and if anything it is probably a step backwards. It doesn't take risks, the scenario unravels and develops exactly how you imagine it would. The commentary on the intelligence community is basically the same as in Captain America: The Winter Soldier.
Then again, it has been a very good year in the spy genre, with three comedy hits in Kingsman, The Man from U.N.C.L.E. as well as Melissa McCarthy's Spy, and so the bar was raised really high. Without so many good films to compare against, SPECTRE is decent entertainment. It is a film with more style and less substance. If you are a seasoned moviegoer, this film might not be very satisfying.
