Being an Al Pacino fan, I thought I would give it a look. Oh dear what a waste of time, such talent, such a shame !!
Tries to echo the crime thriller/mysteries in pursuit of a theatrical serial killer like _Se7en, Zodiac or The Bone Collector_. But it fails. It feels very much as if _Hangman_ intended to take one direction, but ran out of time or was forced to go in a worse direction. It's not complete garbage, but it is bogged down by a very awkward bit of copaganda in the middle, among other problems.
_Final rating:★★ - Had some things that appeal to me, but a poor finished product._
