First things first. In a twist to a famous quote, "You may not agree with what I say but you must fight for my right to say it!"
So, you may have liked the movie but I didn't. Simple. And I will not deny that I thought the movie was disgusting. However much you thought it was hilarious.
I don't like movies that show dirty, shabby houses, toilets, flushes falling on people and such other gross things.
For most of the movie, one of the main characters is struck by diarrhea. Hasn't he heard of antibiotics and other astringents? Worse, hasn't his doctor? Even if they haven't, why take the camera behind him whenever he has to relieve himself.
The worst part of the movie was a scene where they actually show someone pouring out liquid human poop (purportedly, a sample given for a test to a lab). I almost threw up right there. I closed my eyes after one single frame to prevent this.
This, in the name of entertainment? And you have hordes of people loving the movie!
Well, I don't hold any grudges against those who liked the movie. To each, his own! But I found it horrible. Utterly disgusting. A pathetic attempt at humor.
