Just in reply to other reviews...
Just wanted to say in reply to loads of reviews to this, a 'tragedy' isn't to do with how many people dies in something, it's to do with how and why. The london bombings was a tragedy as there are 40 families who have relatives lost, and to them that's tragic, and there are 100s of people who will have this event with them for the rest of their lives. Anyway, September 11th may have been tragic, but America retaliated by killing about 3000 afghanistan civilians, but when'd you last hear anyone mention that as a tragedy?
London has made a massive statement to terrorists by managing to have just about everything back to normal within less than a day, and that's great. I just want to say that to all of you who reviewed this saying London 'deserved' to be bombed, you really need have issues, as no country deserves to have innocent people killed.
By the way, nice movie.
