One of my favourite time-wasters is How It Should Have Ended, a website that makes short cartoons ridiculing blockbuster movies by pointing out holes in their dumb plots and other problems that should’ve been caught before they reached the multiplex. HISHE has brilliantly mocked dozens of movies including Jaws, Indiana Jones And the Crystal Skull, Superman, The Dark Night, Man Of Steel, Star Wars, Jurassic Park and the terrible Prometheus, . Now they’ve gone after Star Trek Into Darkness. The cartoon shows what you get when your movie’s plot has no coherence beyond a surface sheen of cool ideas. You get… trouble.
