I think you probably have to be a huge David Mamet fan to really love this film. I'm not a huge fan, although I also don't hate his works. As for this film, I liked it but didn't love it. The entire film was a character study, and I thought was well done -- mostly. With this cast, I don't think it could go wrong. Robert Forster was fantastic. Some of the humor fell flat for me. Still, I thought it was worth seeing. My grandfather used to work in large ships on the Great Lakes. That's mostly why I rented this film. Although I suspect that his own experiences were not much like this film, it was interesting to me to think that some of them may have been a little bit similar.
