This video will gnaw at you.

It feels like we're flying all over the state of Maine -- and, at one point, we set down on a whim to taxi over to a village where a man sells us homemade root beer out of a refrigerator on his front porch. The only problem is that, although we swoop and dive, circle and fly, we just can't find any moose.

North America has beavers. Europe and Asia have beavers. Britain should have them too, but we killed the last one a few centuries ago. But now they have turned up on a river in southern England. No one knows how they got there, but the official reaction is that they must be captured.

Every time the British guy said the word "deer," the movie showed footage of elk. If the film's director doesn't know a deer from an elk, why should I trust him to get anything else right?

The fisherman wanted his photo shot with a beaver. The beaver had other ideas: It attacked the 60-year-old man with razor-sharp teeth, slicing an artery and causing him to bleed to death.
