A few points:

- Penguins don’t have wings and don’t migrate. What are they doing in this film which is after all about er… winged migration?
- This film opens with a statement that no special effects were used, but over twenty people are listed at the end with “Digital Effects”
- The birds in the film were reared, imprinted on a pilot and then filmed following the pilot as they flew their plane past various “photogenic” sights. In what sense is this a documentary about migration when it is all so heavily manipulated? (Which in itself could be seen as another “special effect”).
- The commentary was pointless, the narrative drive was all over the place, and don’t get me started on the godawful 70s New Age hippy music.
- Nice bird footage though, even if it was felt necessary to uncritically show some of them being gunned down by hunters.
