Watching Mel Gibson as a loving father gone raging madman in Martin Campbell’s (Casino Royale, The Mask of Zorro) 2010 Edge of Darkness doesn’t seem as much a stretch of the imagination as it might have seemed a few years ago. In his first starring role since 2002’s Signs, Gibson plays Thomas Craven, a detective of the Boston Police Department and a single father of one. After Craven witnesses the killing of his 24-year-old daughter Emma (Bojana Novakovic), murdered on the steps of his own by a drive-by shooter, he becomes obsessed with finding out who killed his daughter and, more importantly, why. This movie was a modest success both with critics and with audiences. Still, it made over $100 million less than the 2008 Liam Neeson movie Taken, which is similar in plot but delivers the goods and has you rooting for Neeson. This is more than you can say for Gibson’s character.
