If you are looking for a gorgeous piece of visual art, this is for you. Otherwise, consider these caveats:1. Not all information is correct. For example, the verbal descriptions of characteristics and habits ascribed to yellow-fin tuna are actually those of blue-fin tuna. Another error is the statement that all corals live in tropical waters when, for example, some of the most beautiful coral in the world is off Alaska's coast.2. The gratuitous accent on predation panders to the worst side of us. It gives violence a veneer of acceptability while ignoring predation's benefits, such as strengthening of species and eliminatin of injured or sick individuals. In The Blue Planet, we can be voyeurs to terror and suffering and let our consciences off the hook by claiming "science." In reality, the proportions of this set of DVDs devoted to hunting and killing as compared to other aspects of marine life are way out of whack.
