My wife and I watched this movie at home on BluRay from our public library. It is set either on an island off the Florida coast, or a nearby Caribbean Island where US money is used, but is actually filmed in Mauritius east of Madagascar in the Indian Ocean. Lots of background music is Louisiana Cajun music, an interesting combination.
This movie is really interesting and good but has a somewhat low IMDb rating because many viewers expected a straightforward narrative, I suppose. The opening shot gives us a hint of what is happening, the face of a young teenage boy, then into his eye, which expands to a fishing boat in the ocean. The captain of that boat, the Serenity, is Matthew McConaughey as Baker Dill.
The details can be gleaned by reading any of several user reviews with "Spoilers", suffice to say it has elements that reminded me of movies like "Frequency", "Inception", and "The Matrix." It is woven together well as a young boy, a genius in computer games, tries to deal with an abusive stepfather. But not everything is as we see it.
Both of us enjoyed the movie. I particularly like McConaughey and he is really good in this role.
