These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Alternate Character Interpretation: Exactly how sympathetic you find Nick might change depending on how you choose to interpret his actions and motivations. Do you see him primarily as a dirty cop, or as a mostly good guy who has made mistakes?
Complete Monster: Sato. When other members of the Yakuza think that you are too over-the-top, you belong here. He has two moods: expressionless and Slasher Smile-a-plenty whooping maniac. Acts such as killing Charlie and massacring (or trying to massacre) every criminal big-wig that gets in his way to the top help.
Seinfeld Is Unfunny: While it's a very well-made example of the "Cowboy Cop on the edge out to clean up this dirty town" movie genre, it's still pretty over-the-top. Watching it today shows just how little parodies of that genre have to exaggerate the tropes.
