I just got QoS on Blu-ray, and damn that was a cool movie. I liked it this time just as much as I did when I saw it in the cinema. I also rewatched CR (also on Blu-ray - these are two movies definitely worth seeing in HD) recently, and it blows me away just how much better these two are than any other Bond films have been. I was so over the whole thing when that wanker Brosnan was playing Bond, I didn't even bother seeing the last couple of movies he was in.
Can't wait for the next one!
