I, too, picked the movie out by its description, as I was intrigued to see what would be done with the Everglades, which could have been so much more. On the other hand, that's probably the way it plays for those who go there.
I normally don't like action films, and probably would have felt disappointed had this come from a big studio. But I feel it was interesting as an admirable independent film effort. As the director said in the special features which you should watch afterward, it was a low-budget film made with a big-budget mindset, and, to tell you the truth, it did look very professional.
The plot was interesting, too, not quite what I would have expected. It wasn't what I would have wanted out of a studio movie, either, but had some redeeming angles that you don't usually see in an action film. It did reflect the male mindset, which seems to run to violence, and also a cultural mindset, which I was glad to see did not seem to embrace drug-running but rather universal truths.
I'd say give it an open mind. We're probably going to be hearing more from both director and star.
