There were many nail-biting moments, like the door-opening sequences, and you will want the main characters to succeed because they are so likable. it's not so often that you'll find a film that's so intense & keeping you at the edge of your seat from the beginning to the end. Acting was incredible, Daniel Radcliff and others were very committed to their respective roles, the storyline is that of every prison break film but it's superbly executed here. the score was fitting, and cinematography was good.
