I went to see it on Friday, and I have to agree with what many of the reviews have said- that this is one of if not the best Bond film ever. It has a much more professional style than anything that has come before (the cinematography should be looking at an Oscar nomination come January, and possibly the music as well), it has a top director at the helm, and the acting is on a different level to any other Bond film.
But the main difference is that while it continues many Bond conventions, it is a completely different type of film. It builds a genuine emotional connection with the characters and that takes centre stage particularly through the second half of the film. The villain is both creepy and believable at the same time, and the performance is rightly being compared to that of Heath Ladger as the joker. In fact the whole film has similar story strands to the batman trilogy, which is both good and bad in my eyes. It makes for a great story, but also a story that I feel like I have seen before.
The film is brilliant, and I'd recommend it to anyone, whether you have enjoyed Bond in the past or not. Fans of the film will pick up numerous references to the franchise past, but the film is more than good enough to be enjoyable without that.
