It doesn't happen in many movies, but there's something I like to call the "drop-off point" to describe when a movie turns bad very suddenly. The drop-off point of Hancock occurs at the beginning of the third act and I can't describe it fully without spoiling the ending, but I will say the movie gets bad precisely when the ghetto superhero Hancock (Will Smith) gets thrown out of a window onto a car. From thereon, as fast as Hancock can dive off a building, the movie plunges deeper and deeper into the depths of stupidity and failure.
