Whoever gave the green light to make this film, should be ashamed. Bruce Willis clearly for the past few years, even before his condition was made public, no longer had the competency to act. Yet studios still sign him to make these cheap DTV films to capitalize on his fame and make a few dollars.
Detective Knight's plot was entirely incoherent and uninteresting with no help from the bland characters. It was difficult watching any scene with Willis, as he can only mutter a few words and nod when spoken to. Unfortunately, due to his illness, his personality and charisma are gone. As a consequence, his supporting cast have to frequently say lines most likely meant for his character or respond in ways that hardly come across as an authentic conversation.
I cannot give any reasons as to why anyone should watch this film, even if you are a die-hard Bruce fan. His name is just being exploited here. Go rewatch him in his old glory, and avoid this at all costs.
