Watched this last night
I usually like these sorts of movies, previously enjoyed All Is Lost, which made me find this.
The first two thirds of the movie were great but i found this last third to be a little to harsh, it was unfomfortable to watch and not what i consider 'entertaining'. It was just struggle after struggle and kept getting worse.Whereas in All Is Lost he had difficulties in the journey but most of the part was him waiting to be rescued, the challenging moments felt quick and he moved on to the next.
Still a good movie and will recommend watching at least once.
