Don't. Waste. Your. Time. I watched the first two parts but after the auditory assault that was the vomit/poop scene, I literally couldn't stomach it. I hate leaving things unfinished so I came back and managed to survive the third part, unlike the donkey, but I wished to be put out of my misery as well. You can watch the third part with no knowledge of the first two, it doesn't change anything because the first two parts were unsuccessful in building to anything. You will be left with an open-ended question at the end regardless because after TWO AND A HALF HOURS they didn't even give the movie an ending. This was the laziest of writing. If any movie was the embodiment of hubris, it's this one. It presents itself as deep, insightful and an examination of society. But in reality, it is empty and relies heavily on cheap humor and beats it's own points into the ground with the grace and force of a elephant stamping out a fire.
