Although I have seen the movie years ago when it was on cinemas across the world and of course on dvd several times, I bought the blu-ray version in order to see the difference. I must admit that the experience was incredible and during the scenes that John Travolta was firing to the FBI agents and Hugh Jackman was driving, it was like that I have been on the street, in the middle of the crossfire.

If you want to experience the blu-ray difference, I strictly recommend the movie. That's how you see the development from DVD to Blu-Ray.
