After seeing the film myself and the other comments on your review, I agree that you have taken an unnecessarily harsh and inaccurate stance against an amazing true story told by people who clearly were dedicated and invested in the story they told. And they told it quite beautifully, if I do say so myself.
Clearly this was an independent film, but you can always tell when something was handled with care, and this film was told with extreme care and attention to detail. A little research on your part would have shown how much research went into the film's creation, as well as the fact that they used a real, operational B24 to film the movie. It's not often that you see an actual B24 bomber plane flying over the ocean or the real interior of the plane used throughout a film. The efforts of all the people involved in the film brought to life an incredible true story that more people should know about.
So rather than make rude comments about a film that didn't have a super high budget, you should be appreciative of how creatively and carefully the funds were used to honor these American soldiers and their bravery. If the veterans who were there stand by it, who are you to say that it wasn't "entertaining" enough for you? Maybe you should think before you lash out next time and consider who you might be disrespecting.
