A buddy cop movie with a seasoned old hand so close to retirement they’re already scraping his name off the door and his hotshot, firebrand young replacement, this couldn’t be further from another Lethal Weapon. Yes, one’s a family man and the other’s a loner, one is prone to anger and the other a methodical, careful detective clearly too old for this shit, but where Richard Donner’s 80’s staple is an entertaining, action-packed romp, this is something much darker.After a disturbingly evocative opening credits sequence enriched with depth and meaning on repeated viewings, we meet Morgan Freeman’s detective Somerset, picking up his last case, a sickeningly masterful serial killer with a penchant for the seven deadly sins, the same day as Brad Pitt’s Detective Mills arrives to replace him. That’s as much setup as there is, as we follow the mismatched detectives from crime scene to crime scene, via their headquarters and areas of research, with Somerset whiling a night away poring over books in the library, whilst Mills take a brief glance at the Cliff notes.

The script is dotted with well balanced moments of humour – Somerset having dinner with Mills and his wife Tracey (Gwyneth Paltrow) – and some deep black humour: “this guy’s sat in his own piss and shit; if he wasn’t dead he’d’ve stood up by now,” plus R. Lee Ermey’s belligerent, furious Police Captain (“This is not even my desk” is one of my favourite film quotes, ever).

Crucially, we see none of the killer’s murders onscreen, merely their gruesome aftermaths. It’s not as gory as you might remember, but it evokes imagery and feelings that some may find disturbing, not least what happens to Leland Orser’s character, who probably has the worst memories of those who survive. It could be argues that this is a precursor to the Saw franchise, punishing those that seem to deserve it in creative, torturous ways, but at least here we are saved the nightmarish spectacles of witnessing the deaths.

At times the film feels a bit predictable, like a police procedural itself, but whenever this is about to happen the plot shifts direction, taking an unexpected twist to shake things up again. The colour palette of muted greys and browns, interspersed with deep reds amongst the incessant torrential downpour of the nameless city only adds to the feelings of despair.

There’s small roles for John C. McGinley and Richard Schiff in there as well, a nice surprise for me in the opening credits, but unfortunately at times the acting, especially Pitt during the final scenes, leaves something to be desired. The ending has become the stuff of legend, but I won’t reveal it just in case, save that Pitt’s gurning and crying are a bit over the top and take you out of the scene. This is another one of those films where knowing your actors may ruin the film too, as recognising a voice could cause annoyances later on, but not too badly.

Overall this is director David Fincher’s defining film (better than Fight Club in my opinion, though it’s been a while). The gritty tone is perfectly realised through every medium possible, the plot is gripping, the twists hold up and, though far from an enjoyable experience, it remains worthwhile.
