Four words 'deoxy ribo nucleic acid' or DNA. Did the writer forget about about this? I asked myself if detectives and police could be this stupid, because if the answer was yes i don't think any crimes would ever be solved. This movie was boring and I called the ending with about an hour left in it. If you are the kind of person that picks up on detail when you watch a movie, you're gonna hate this as you will easily foresee the ending.
