I got to watch it today since it just hit the big theaters here. (Yes, the price I pay for living in Japan...!)
Quantum of Solace is a fantastic Bond flick. I loved it. I know some people complained about Bond being too dark and/or the character development relying too much on what happened in Casino Royale. But I always thought the lack of continuity and Bond's development were weaknesses rather than strengths of the franchise; there's something very callous about him not caring about all those dead Bond girls, etc. So I didn't mind that Vesper's death played a significant role in Bond's character in Quantum of Solace. As a matter of fact, I thought it deepened the movie and Bond as a character. Besides, the kind of work he does is dirty and not supposed to be light and fun. Read Fleming's novels; Bond might be a playboy, but there are other, dark sides to him too.
BTW -- the theater had some technical difficulties, and the movie had to be stopped in the middle for about three minutes. For the inconvenience (for which they apologized in person four times), they gave everyone a voucher for a free movie ticket valid until April 30. We can choose any film we want. W00t! 
I think I'll save it for a reward day.
