Blue Planet II has all the majesty of the Planet Earth series and is a worthy successor. Also--I already knew marine mammals and cephalapods could be pretty smart, but I'm just amazed at the apparent intelligence of some of the fish in this.

The more of these BBC wildlife docs I watch the harder it is to write reviews for them. Normally, if you know exactly what to expect from a piece of art, that's considered a bad thing, but in this case it isn't: You expect beauty, majesty, some educational nuggets and the soothing dulcet tones of David Attenborough, and that's exactly what you get. And I loved every minute of it.

This is exactly the definition of "majestic".I love BBC documentaries. Its not just taking some record about animals or ecology. BBC Documantries are really the pieces of art.

Watched One Ocean and Big Blue with my child, it was perfect watching with him (the documentary elements didn't overshadow the visuals and there was minimal violence). Beautiful, seamless, and wonder-inspiringly beutiful

David Attenborough should be my husband.

On the same level as the original Planet Earth from memory, though some of the foley work is a bit overbearing (e.g. putting 1950's UFO-style theremins over the shimmering cuttlefish). Still, it's fantastic and one of the best nature documentaries you could experience.
