The movie was a good concept - an alien life force in the body generated by DNA taken from a human during a visit to earth some 90 yrs or so earlier. An all powerful alien - who could manipulate anything and anyone. But just when it could get dark and interesting, it turned predictable. The "green" message could not be lost on even the most obtuse viewer. The whole "human race overcoming the odds and being better." The effects were cool though.
The movie does live up to its name in that it is truly dark. Helath Ledger is truly convincing as a madman - consistent in his potrayal as the Joker. Saddening to think that, despite what others may avow, this work contributed to his loss of life. Christian Bale did not connect with the screen or the role and was detachingly boring. Still it was entertaining for adults - way to heavy handedly blase about the violence for children
