I recently watched the 'The Road to Peredition' for the first time and thought it was pretty great. Jude Law was good at playing the creep who kills and photographs his victims. The revenge story was great and I'm surprised it took me this long to see this "gangster" film. I also did not know this was a Sam Mendes movie, which explains a lot about why 'Skyfall' was so damn good.
It led me to watch '1917' which was incredible, I always forget about WWI and just how brutal that war was. The long camera shots really put you in the action and it holds you there until the very end.
