• I imagine this lost a lot going from the visual power of 3D IMAX to my 60 inch 2D monitor, And it's 40 minute running time limited how deep it could go. (No pun intended). But it still was enjoyable – a well done wildlife documentary, focusing on the wild feeding frenzy that occurs most years along the eastern coast of South Africa, as giant clouds of hundreds of millions of sardines gather in search of food, bringing in turn every kind of imaginable predator in turn to eat them: sharks, dolphins, whales, sea birds, seals, and – of course – man.

    Humans have fished this phenomena so heavily that the numbers of sardines has started to drop in recent years, and at the same time global ocean warming has started to change the sardines' geographical migration patterns.

    All this is interesting and (or course) very well photographed. But probably because IMAX has to appeal to young kids as well as adults there's not the kind of depth of specific scientific information you might find in one of those BBC/David Attenborough documentaries covering the same subject.

    Worth seeing, but probably far more so in it's natural habitat of a 60 foot IMAX screen.
