During the 70s Wolfgang Petersen directed a lot of thrillers for the popular German TATORT-TV-series(ca. 90 minutes long episodes, e.g. Tatort - Reifezeugnis). Most of them were suspenseful and credible. Seeing SHATTERED you wouldn't believe it's the same director. I mean, twists can be nice and add to the entertainment value, but what we get here is really incredible. Most people seemed to have enjoyed this one, though. Switch your disbelief off!
