Basically, this is a mediocre movie. I was primarily led to watch it from comments that the setting was the Grand Canyon and that the cinematography was good. However, apart from a few shots of descending into the Grand Canyon, the rest of the story was actually filmed near Moab, Utah, and not in the Grand Canyon. The slot canyon in the movie was Antelope Canyon near Page, Arizona (also not in Grand Canyon). There are slot canyons in Grand Canyon (such as Deer Creek and Matkatamiba) but they are a lot harder to get to for filming and are not seen in the movie.
Moab is certainly a beautiful place, but for those familiar with the territory it looks nothing like the Grand Canyon. It is understandable that the movie was filmed in Moab rather than in the Grand Canyon because Moab is much more accessible and filming there would be cheaper and easier on the personnel involved. But those expecting or wishing for a movie filmed in the Grand Canyon won't find it here.
