I was quite intrigued by the trailer for this. Somehow, though, they seem to have managed to squash all that's interesting about the film into it... It reminded me a great deal of "Se7en" (1995) with Denzel Washington "Deke" a former detective with a history that resulted in him being relegated to a rural uniformed role. He is despatched to the big city to collect some evidence whereupon he becomes embroiled in an investigation led by the cocky "Baxter" (a rather wooden Rami Malek) into a series of brutal killings. The title of the film is the gist of Washington's character - he is methodical a... qalǵanyn oqý.
