The movie has a great beginning and drags you into it. However, the conclusion and what we are waiting for is.... who is the killer. Well they never found the killer and the two detectives basically where both terrible at their job. The case remains open. Ok what in the world the writer was thinking off... terrible ending. Word of advice. 90% of humanity don’t like breaking their heads on these crazy dumb ending. Just keep it simple and have a killer caught, kill or live it for a open for a part 2. Terrible.
