I for one found the Thriller very exciting. The idea itself is not entirely new, and they are certainly seen in several films ever. However, does not bother further. Until the middle of the film the tension was gradually increased until it quite clever occurs after a small twist content and thinks that one could foresee the future course. But it unceremoniously followed by another twist that surprised me a lot personally. I usually find a bit annoying films in which follow often surprising twists to each other. In this case, I think it has done extremely well the action. Definitely recommended.
