This is one of those rare movies where the scenes are cleverly written and mean something, not just space filler. It does not waste your time and I really appreciate that. The two lead actors are each very good and perfectly cast for their characters. You frequently ask yourself, how would I react, how would I respond, am I like that and other questions. It's rare to see complex, unsettling, destructive high intelligence portrayed well on the screen. It felt exciting to watch.
