Blue Planet 2 - David Attenborough

Unlike the first Blue Planet, the episodes here are more separated by the depth of the ocean. The final episode looks at our impact on the ocean: good and bad.

The quality of the footage is breathtaking, a huge leap forward from the first Blue Planet. The series focused a lot more on the volume of life and how much is in the darkness.

There is a lot of focus on the unknown and recently discovered.

There is an incredible section in the deepest part of the ocean where a probe is dropped into the Mariana Trench. A fish can be seen moving around in the depths a thing that was thought to be impossible at such pressure.

The hydrothermal vents were amazing—especially the fact that the variety of life around these dwarfs that of rainforests.

The footage of the lost city vents was eerie especially as they were talking about it being the origin of life on the planet. This is because hydro-carbons spontaneously form because of the intense heat and pressure.
