Stunning, awesome, unbelievable! I can’t find enough superlatives for this film. There is no dialogue, no real story; you fly with the migratory birds, right among them. I wish I’d seen this on a big screen, but then I would definitely have rented the DVD later, as well, because there is a documentary on how it was made that is about as long as the film itself, and just about as amazing. The things these filmmakers did, over about four years, are almost beyond belief. See it!
