We saw it this weekend. I liked it but because we watch so many ocean documentaries, I didn't learn anything new. I think it would be good for kids, though. There really wasn't any sad scenes. They show an Orca and a shark eat a couple of sea lions, but it's not gory. I actually thought they didn't do enough to show man's impact on the oceans and how we're killing them. It barely touched on the warming earth and ice caps melting and BARELY showed the trash piles in the pacific. In fact, they didn't even state how large the trash islands are (the size of Texas and 90 miles deep). They did show that other animals get caught in nets, so that was good (well, bad). But all in all, I thought Earth was better because they followed a few families and showed their stories, but this one they didn't follow any specific families where you would get hooked on their story.
