Moody music, mumbled dialog, grainy photography - do not necessarily make a movie a work of art

So we sit down with the fam last night to enjoy some good quality time watching a movie about a serial killer - and what do we get? A pretentious, crappy movie in which the villain (spoiler, I guess, but if you can't figure it out why are you even reading this?) turns out to be the evil SHOPPING MALL DEVELOPER! Gosh, why don't filmmakers leave these guys alone? All they wanna do is make shopping better and more convenient for everyone. So what if they clear away slum housing to build their palaces? Does that mean they also have to be child molesters, too? I'll never see a shopping-mall developer again without a shudder of fear, thanks a lot. The movie - "Red Riding Trilogy Part 1: 1974" - is allegedly, supposedly based on the story of the Yorkshire ripper of the 1980s, but a quick look at any reference will give new definition to the word "loosely," as this killer is a child molester and torturer, not a slayer of prostitutes. Just call it a series murder investigations and police corruption - at least that would be more honest. It starts off reasonably well, but becomes increasingly preposterous as the plot unfolds - one of those stories in which the improbable hero (in this case, a journalist eager for a scoop) - endures way, way beyond the possible realm of physical endurance, and ultimately you have to say: why don't the bad guys just kill him? They've killed everyone else? They obviously leave him alive just so that there will be a story. All the moody music, grainy photography, and mumbled dialog in almost incomprehensible dialect will not turn an ordinary police procedural into a work of art, sorry.
