text: I admit to being in awe of the Sea and have spent a number of years in the Navy, so I am somewhat biased on this one. I missed this documentary when it first came out but nagged various people to buy me it on DVD this Christmas (2002) and I got it! Some of the film is amazing and I have a lot of respect for those who make these kinds of documentaries, to see 200 ton Blue Whales 'cruising' through the Sea is an incredible sight, they looked like submarines. I like the level of information and facts conveyed through the narration, it is just right, I don't want to know a load of science just some of the basics, to see these things is enough for most people. The BBC has a knack of putting things at the right level for the intended audience.<br /><br />A really great documentary, up there with 'The World at War for' me, the DVD is of excellent quality. If I had a minor criticism it would be some of the obviously added sound effects here and there, I think they detract from some of the scenes. But well done to the BBC and Discovery.
