This documentary from Morgan Spurlock is unlike other films I've seen of his. He does not appear in the movie at all nor is there any narration. Considering the subject, I can understand both decisions.
The film is all about rats. Much of it centers on the health risks caused by the creatures as well as the impossibility in completely eradicating them. This part of the film was creepy and disgusting but also very informative and interesting. There also were portions about cultures that eat rats, folks that revere them and folks using terriers to hunt them. The film takes the viewers from New York City to New Orleans to India to Southeast Asia to the UK.
So should you watch it? Well, yes...provided you aren't squeamish. You'll see lots of dead rats, rats die and a few decomposing mammals. Not pleasant stuff, granted. But still, despite the creepiness and awfulness of some of the material, it's worth seeing and very well made.
