Dirk Diggler’s review published on Letterboxd :
Many films try to be cool, but very few ones reaches this level. It surely helps that its starring Alain Delon, probably the coolest man of all time, his moustache is glorious. The heist sequence is extraordinary, obviously inspired by Rififi as it's similar in execution, but I actually preferred Melville's. Also loved how they barely explained anything beforehand on how to accomplish the heist. I love Melville's simplicity and understatement, his patience and use of silence, the meticulous and slick execution void of sentimentality, the somber yet cool vibe, and his way of making everything flow so smoothly, but I can't help but feel slightly underwhelmed by this one, hoped for a bit more - it lacked some punch. Anyways, great stuff and awesome to catch it in the theater!
