Mystery/thrillers can sometimes put themselves in a bind. They create a 'did he/didn't he' scenario and base their movie around it, but the problem with that is if the answer is one of the options (usually "he didn't") then you don't have a story worthy of a movie, and thus the answer is simple to work out. 'Spinning Man' finds itself in this predicament and takes a unique route to try and escape it. Did it work for me? Not really.
You leave the film with a little bit of a "what was the point?" mentality. The film being quite well made actually covers this up partially, but it's still there lurking at the back of your mind. The film is at its strongest when it is creating psychological parallels with the story that is going on. It's easy to tell the film was based off a book, because it is very well crafted in that sense. The acting from the main three - Guy Pearce, Pierce Brosnan and Minnie Driver - is also very strong and helps carry what could otherwise have been some very clunky dialogue in places.
The film shares a lot of similarities with 'Memento' (and no not just because Pearce is again in the lead role) yet it too often feels like an episode of 'CSI: Crime Scene Investigation'. The pacing is a little lazy in spots which creates this feeling. This is far from must-watch material, but there is still enough here to make for a perfectly passable film.
