1) This is the best view I have yet seen of Sealand's facility, and its various pools, including the module. In addition, you can seen how tightly surrounded by a major marina Sealand was, which adds to our understanding of what life at Sealand might have been like for Tilikum, Haida and Nootka.
2) There is a very good view of how the module and its gate was connected to the main Sealand pool. And you also get a sense of how small the Sealand main pool was (just 100 feet by 70 feet) for three killer whales.
3) There are some good shots of Haida's newborn calf, Kyuquot, swimming in the main pool.
4) There is an extended shot of Tilikum quarantined in the module. This is the best footage of the interior module I have come across, and you also get a sense of how small it was for him. So small, in fact, that he is forced to surface rest the entire time. And you can see how the skin around his blowhole, which remains above the surface, is drying out (a point SeaWorld used to argue his health was at risk at Sealand).
