Review of Hangman

So it wasn't my imagination or the idea that I might have missed something. The first four serial killer murders in this story proceeded along in a credible enough manner, but then things got weird when Detective Will Ruiney (Karl Urban) and retired cop Ray Archer (Al Pacino) found the guy who was tied to a chair with the back of his head blown off. From there it just sort of staggered to a conclusion that didn't seem to tie together very well. I think maybe Archer was on to something when he said to his partner at one point - "You want this thing to make some kind of sense"? For us viewers it would have been a good idea. Oddly, it seemed like tag-along journalist Christi Davies (Brittany Snow) did more to contribute to finding the killer than the two cops. If indeed they did get the killer. Because the ending suggested that they never put away the right guy for the murders, an ending about as expected for this type of film as it was moronic.
