The movie is really intense. It's an edge of the seat thriller, constantly making you nervous with it's high tension situations. Adam Sandler is a revelation here, this movie makes up for all the horrible films he did in the last 10 years. The script & direction is on another level, hats off to the Safdie brothers.
The ending hit me real hard in the gut, I wasn't expecting something like that, I felt sorry for Howard, best ending possible I guess.
