I was a sailor. Sailed to the Arctic circle, Bering Straits, both Tropics, and did the 'crossing the line' of the Equator 'ceremony' several times (no, I never met Davy Jones). Plus, Southeast Asia and some Middle East stuff. Also Australia...Perth and Sydney.
I liked the movie for what it is. A movie.
This is NOT a documentary of Jessica Walter's voyage. Spoiler alert given.
Still probably one of the best movies I've seen on Netflix in a while.
It'd be interesting to see if Jessica would repeat the voyage at some point in the future.
