At this stage we actually do not know how and why Heath Ledger died. It may turn out to have been a tragic accident, or a mixing of prescription drugs with fatal consequences, rather than anything that can remotely be said to resemble your archetypal sex, drugs and rock and roll exit from life. Repeat, we just don’t know.
People who improve on the shining hour, then, by sermonising on his death tell us more about themselves than they do about Heath Ledger, life, God, religion, or Jesus Christ.
