I enjoyed it but I'll barely remember this movie in 2 weeks. It's not special but I just love the exploring Amazon genre, especially if it includes even a hint of based-on-a-true-story. Charlie Hunnam did a decent job in lead. None of the other characters had deep meaningful roles, at least not until the very last segment with his son. Four stars because I love the genre and hope for more exploring-the-amazon movies (but maybe a bit deeper).
