As far as being lost - nope, just a know straight line couple of hours boat ride between big towns. How sea, air & land rescue teams could do nothing is not too believable. The trekking by our lost & searching peoples seemed artificial. Acting - not required. A few seconds of fire making using wood friction was dumb.
Not staying in the boat - a made for making a movie decision. Oh, thought it might be "based" on a true story - nope.
