'Great Migrations' (NatGeo)

One animal is cool, but hundreds and even millions of them traversing the earth at once is a stunning, humbling and occasionally horrifying endeavor to witness. Observing nature never fails to move our jaded critics hearts, especially when it's 50 million tiny red crabs on Christmas Island, tap dance-scurrying over rocks to begin their lives.
