I feel this movie was made by some sick guy that wanted to exploit all things wrong with rats. He turns them into terrible creatures that will rip off your face, when that's simply not the case. While I believe some facts of the movie are true -Spoiler: They do carry diseases, they are a threat to humans.- They forget that they are just creatures doing the exact same thing we are; Surviving. Wild rats were meant to live in much harsher conditions than we provide, hence the massive litters. Since the food supply (our trash that we poorly manage) is so massive, they are too.
This, however, is not my main issue. Spoiler: The experiments are. The host of the movie stated that he put a bunch of rats together in an enclosure, THEN STARVED THEM. JUST TO SEE WHAT WOULD HAPPEN. What the f is wrong with him?! Of course they'd become cannibals! So did we during the Crusades! Overall, this movie promotes hatred towards what can be beloved pets, and turns them into monsters that they really aren't.
