Not your normal 'summer blockbuster', this movie has levels and elements within it that set it apart from those that have come before it. There is something compelling about the good and evil in each of us, but told through the context of fear and personal choice. What will each person do when confronted with the choice between personal loss, including death, and/or loved ones? I was very engaged by Nolan, in how each of the key characters had a part to play and act when in this situation. Ledger was so compelling that each scene played seamlessly and the nuances were totally believable. Well worth seeing before any other movie this year!!
