. it have the potential to work . combine it with an actor who apparently want to make one of those film you can tell be specifically create for oscar award nomination and end up be cliché and simplistic and you get cliché and simplistic and and unrealistic . at time it do work . but i think this be a case where the director ( also a primary actor in the story ) get himself too involved and lose perspective . you could also say this mix the various sniper or killer film popular at the moment with an xmas film . either way and the end product would have benefit immensely from someone review it who wasn not personally involve in the film and a bit more plot development .
