For my money, the best movie about life under the sea is Finding Nemo. Marlin is looking for Nemo. Dori lost her mind. And the sea gulls just want to get what was theirs. There’s a lot of moving parts in that story, but my big takeaway was “all drains lead to the ocean.”And it’s true. All drains do. Well, almost all of them. There is the odd inland sea or landlocked lake. But other than those few exceptions, drains have been moving water to the ocean for more than 5,000 years.
