The whole "amnesiac finding himself accused of murder and setting off his own personal investigation to prove his innocence" has been done before, but I was willing to sit through it again. However, these filmmakers weren't able to put enough freshness or common sense into this retelling. As other IMDb commenters have stated here, the plot in this retelling has a number of holes. Some things are not properly explained, and other things simply don't make sense if you know how professional police investigators (or even ordinary people) act. But there is a bigger problem with the movie, and that is how slow and dull its story unfolds. There is almost no feeling of struggle or tension in the entire 92 minutes, and as a result the story is so low key that it's hard to give a hoot about the mystery or any of the characters. The problems with the movie may have in part come from the fact that the credits state that two people directed the movie; conflicts in the director's chair may have taken attention away from the fact that the screenplay and its atmosphere needed a lot more care.
