I found the movie so breathtaking and real as I got an insight into Zimbardo's aim in investigating how social roles affect conformity and I clearly found my answer that humans are innately challenging and unbearable and primitive, we act according to our ID which is part of our subconscious mind. Everyone who hasn't watched this needs to right now - it's completely different from what you've seen before, its an original that I know many of you guys will enjoy despite not being fans of thriller and drama types of movies, some of you. Take the risk! Be bold!!
