A good ending was missed

Rating: 7/10 (29 July 2018)

One review noted how bad the sound was. I could not hear much of anything in the first ten minutes. I kept turning the sound up and then a gun would go off and hurt my ears. This was such a hassle that I turned on the subtitles & left the sound alone. This was a serious technical flaw that is surprising today.
I thought it was a very good movie until the standoff at the drilling site. The gun fight made almost no sense and it seemed pointless to kill so many people. The scene could have involved fewer people and been menacing and very tight.
The big opportunity missed was when Renner's character tracked down the killer, Pete, and got him to confess. When he let him go to walk barefoot in the snow, the ending would have been a lot more satisfactory if Pete had collapsed and the last thing he saw was the mountain lion and her cubs fixing to have dinner.
I gave this seven stars because the critical moment was too lame, too Hollywood, and not effective. The sound track was terrible and there is no excuse for that.
If sound had been better and that scene at the oil rig had been tightened up and more realistic I might have been given this eight stars. If the lions had gotten to feed on Pete, it would earn nine.
