Being a scuba diver of over thirty years, I was keen to see this documentary when it hit the cinemas here in Australia, and wasn't disappointed...!!! The film is superb, especially the great detail shown in the high definition undewater footage shot by Rob.I highly recommend this dvd to anyone interested in preserving our underwater environment and trying to help stop shark finning by the asian countries. Full marks for this film.Barry Streete,Newcastle ,Australia
