Let me start by saying that I love the James Bond universe as a whole. There are things about it that I don't like, such as how the action is a weird combination of over-the-top and realistic action (I typically like my action movies to go one way or the other, not float around in between), and a few other things here and there, but I love Bond as a character, and I like the inner workings of the James Bond world.
That being said, I did not like Quantum of Solace very much. It had almost none of the qualities that made Casino Royal so excellent, and it added some qualities that made it worse. It was basically just a straight up action movie this time around. Bond never stopped moving, and there was really none of the cerebral, psychological thrill that there was in Casino Royal. I was never in suspense of what was about to happen, I was just waiting to see how Bond was going to kick an ass. The action wasn't even all that exciting. It was just run-of-the-mill explosions, gun fire, and the occasional chase.
Also, let me say something about technology in movies: Gigantic panes of touch-enabled glass are not the wave of the future. They are impractical, unnecessary, and no organization geared towards efficiency (such as MI6) would even think twice about wasting time and money on something like that. So stop it.
I dunno. Quantum of Solace was entertaining in the fact that it gave me something to do for two hours, and it certainly wasn't terrible. It was still shot fairly well, the special effects were high quality, the plot was fairly interesting, and Daniel Craig is still a great Bond, but overall, it was just lackluster.
Verdict: Watch if there is nothing better to do. It will keep your attention for a couple of hours, but don't expect a whole lot.
