Quantum of Solace was a big disappointment after Casino Royale.
Spoilers:
There was a lot of action, that's not bad. But fast cuts, swinging the camera randomly and being out of the focus made it difficult to watch all this action. The plot was way too simple. There was no twists at all. Having read that in this movie Bond goes totally Rambo and kills in rage avenging his dead girl, I was somewhat surprised that Bond didn't really kill so much. All the killings that M ranted about, were pretty much "kill-or-be-killed" kind of situations. And when Bond finally had his chance for revenge, he just gave up. I wanted to see rage! RAGE! Ok, he killed the bad guy. But being the final boss fight, the match was so uneven --and uninteresting. Bond vs. squeeky nerd. The Greene didn't have a chance. A cool henchman would've been great, but instead of coolness he had went with the guy who wore a collar half of the movie and had an awful haircut.
