Midway Gear Shift

Isn't it always intriguing when a movie separates its plot strands into isolated portions of itself? A plot is abandoned midway through in favor of another, or completely separate plots are held together by merely a thin sequence of events. It often creates a huge tonal or even entire genre shift that makes the movie a real rollercoaster. Unfortunately, for conventional marketing purposes, often necessary, the turning points in these films are either spoiled before we see them or concealed, which either makes for an unsuccessful turnout on account of not giving audiences what they've expected or keeping people away by advertising the film as much more dull than it actually is. Adult cartoons are hugely successful for the inherent potential for both absurdism and bullet-paced attention span of this device.
