The movie starts out kinda slow and predictable. Then, you get an Ah Ha moment that picks up the speed of the movie and delivers an incredible ending that will leave you talking about it for some time after. The ending will make you think.
Overall, the acting was fantastic, Scorsese does great job at picking people and directing them. The scenery is beautiful in a depressing way, maybe even frightening to those that have ever been scared of a place like that.
