The film I most recently saw that had me really rather annoyed was Babel, which seemed to rely on just about every character being a complete moron in a rather coincidental fashion. One 'tragic' incident should be enough to base a film on. Stringing a dozen of them together in a single film is not only highly unlikely, but also shows a weakness in plot.

Having my sister next to me defending the film's inadequacies infuriated me further. I have absolutely no time for morons and those that defend them.
