I'm disappointed in the lack of symmetry. There are so many episodes on: Shark Attack; Shark Predators; Shark Attack Rescuers; 10 Deadliest Sharks; Shark feeding frenzies; Attacks in Cerife, Brazil... etc..
However, I've only seen one episode dedicated to the plight of the sharks... The finning off Costa Rica, and Papua... The decimation of 100 million sharks a year.... They keep saying what a shame that is, and how everyone's tagging sharks, but have yet to explain what the disappearance of sharks could mean to the ecological balance, and health of the marine ecosystem in general.
It's all fabulously interesting ('specially the diving sequences)... However, how 'bout a little less sensationalism, and a bit more of: "...this is what it would mean if the slaughter continues..."
