Interesting facts about the geography, history, and animal life in the Atlantic. This is mostly an animal documentary, but provides an appropriate amount of contextual information - how the atlantic was formed, a little bit on the use by humans, etc. The first episode focuses on the Gulf Stream, which acts as a story line for that episode. I quite liked that it provided a natural flow to that episode.The documentary is not up there with the best of BBC, but definitely high quality, with very good camera work - particularly up-close to the animal action.I would have rated this documentary higher, but have rated it down by at least 1 star because of the sleepy narrator voice. He almost sounds disinterested, but at least he is good to understand and not cheesy.
