A far cry from the book it is based on. Very superficial, no detail, no character development, fake conflict, and the characters themselves are not what you'd expect from the book. And I do not recall seeing in the book that Thor could not swim, but perhaps it was mentioned elsewhere? In the book he gets into the water around the raft just like everyone else, i'd be surprised if he could not actually swim. The book is not great either, he is not the best writer but at least it gives a much better glimpse into what was really happening on board the raft and what their daily lives and interactions were like.
