Holy gripping dialogue, this is my facorite kind of movie. Theres no need for anything exploding on screen, the writing does all the heavy lifting. Only thing that could be better is the acting imo. If it were me writing, I sure would've used a bit more characterization of Oldman's memories by the olfactory nerve considering it's the first-formed and longest held memories we have--smell.
Definitely a sit down and think movie you won't regret.
