I saw the movie about a week ago and very much enjoyed it. I agree with the others that describe it as a great story that happens to be set on a sailboat out on the ocean. If you are going to see it solely for accuracy of the sailing piece, you'll likely be disappointed. That said it was pretty accurate in most of what it conveyed. For me, I really liked the story and the acting (who knows but Redford could win his first acting Oscar for this one). The fact that most of the story occurred on a sailboat and showed a single handed sailor doing many of the mundane things we all do aboard (and later in the movie not so mundane emergency procedures) I thought was incredibly unique for a feature film.
They also serve beer/wine at my local theater – what’s not to like about the whole experience?
