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.
Complete Monster: Brick Top's Establishing Character Moment shows him ordering two Mooks tasered and suffocated with plastic bags, after which they are to be dismembered and fed to pigs. He shows even more of his ruthlessness as he shows absolutely no compunction about having a clan of Irish Travellers murdered if one of their number doesn't fight for him in a rigged boxing match and orders the fighter's mother burned alive in her trailer for demonstration. There are two kinds of characters in that movie: those who have never heard of Brick Top and those who are terrified of him.
Moral Event Horizon: In response to learning that Mickey wants a caravan for his mother in exchange for fighting, Bricktop responds by having Mickey's mum's caravan burnt down. While she's still in it.
Nightmare Fuel: Just... Brick Top in general. Particular mention goes to his calm, matter-of-fact lecture on the best method to dispose of a body.
Brick Top: You're always gonna have problems lifting a body in one piece. Apparently the best thing to do is cut up a corpse into six pieces and pile it all together... Then I hear the best thing to do is feed them to pigs. You got to starve the pigs for a few days, then the sight of a chopped-up body will look like curry to a pisshead. You gotta shave the heads of your victims, and pull the teeth out for the sake of the piggies' digestion... You need at least sixteen pigs to finish the job in one sitting, so be wary of any man who keeps a pig farm. They will go through a body that weighs 200 pounds in about eight minutes. That means that a single pig can consume two pounds of uncooked flesh every minute. Hence the expression, "as greedy as a pig".
One-Scene Wonder: The agent at Brick Top's bookie's (played by an uncredited Sidney Sedin), whose attitude during the entire robbery scene can best be described as "bored resignation" whether explaining why there isn't any money or thwarting the robbery single-handedly.
Wangst: Everyone can be accused of this. Brick Top and Cousin Avi in particular.
