Agee with what you've all said. We were shouting at the iguanas to get a bloomin' move on! God, those snakes... Just oozing out of the rocks like that! And poor penguins and crabs having their eyes eaten by the ants (brought to the island by humans, grrr).
Trouble is, I find myself welling up every time I see David Attenborough, I really can't bear the thought of him not being around... he's like a beloved family member.
