I liked you couldn't guess or pinpoint a subject and when you do its was the wrong subject.

Great! Action packed and very suspenseful.

The opening was great. It set the mood for the idea of a commuter train, day in and day out.And one day everything changed. I was riveted as the caller knew every detail of what went on. Just when I thought I new who was the 'bad guy' , I didn't.Exciting and fast paced through out. Total shocker!.

A great movie that will have your attention all the way through!
