Alan Partridge famously cried out "Stop getting Bond wrong!" They got it right this time, in several ways.
Brilliant performances from all the cast, including a memorably disturbing villain, nice humorous moments and tongue-in-cheek snippets of dialogue, exciting setpieces, and (very importantly) a catchy and memorable theme tune.
It's up there with the best of the Bond films, and it's to its credit that it has a modern, multi-layered, subtext-filled storyline that, more than the '06 Casino Royale, seems further removed from the standard Bond formula we've grown up with than most others' attempts.
If there was one gripe, it's that it didn't have quite the same impact on me as Casino Royale when it came out - admittedly to produce the same reaction would be very hard to do. But it is a minor feeling - the film made the most of the two and a bit hours' running time, and by the time the final scene of the film took place (which in itself was a wonderful final tribute to the 50-year film series heritage) the action-packed opening in Istanbul seemed like an age away.
In short: Quantum of what now? This was amazing, and definitely worth all the hype.
