So it's a MUST see for anyone into nature photography and documentaries. Note it may be a bit much for kids who have a hard time with animals getting eaten. There are some graphic scenes of baby sea lions getting nailed by by killer whales, a pack of killer whales working together to kill a grey whale calf, and other scenes of predators in action: rays, sharks, octopuses, etc. My 5-year old cried during these parts; we lied and told him the calf got away (he wanted to believe this so ignored the graphic evidence to the contrary...). Also the DVD is not exactly educational. It's mostly amazing photography with little dialogue. Kids probably should start off with some more educational DVDs and trips to the aquarium to really appreciate this.
Rented from Netflix, but it's available on Amazon.com too (they have a dorky Penguin cover; for the blog I used the cooler BBC one). Note that Deep Blue is basically photographic highlights from the 8 hr series Blue Planet (2001) also available on DVD at Amazon. Blue Planet
