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.
Crosses the Line Twice: The whole damn movie. Shooting an innocent cat? Utterly despicable. Accidentally shooting a cat, and reacting with a Cluster F-Bomb? Very funny. Attempting to conceal the blood splatter on the wall by taping a (much too small) piece of paper over it? Fucking hilarious.
The piece of paper is a picture of the cat.
"Is it dead?"
Ho Yay: Connor and Murphy are very close. Somefans point to the scene where Connor rips a toilet from the floor in a frenzy and carries it up to the roof to drop on his brother's would-be killers when Murphy is in trouble, as well as jumping five stories down to land on an attacker as a sign of their profound love for one another.
Also the cauterization-by-iron scene where Murphy is holding Connor still from behind. They all got gagged to refrain from screaming, which reduces it somewhat... until Connor reaches behind and clutches at Murphy's hair while the camera pans over to leave only the two of them without even the iron in frame. Thus, it is extremely easy to take that scene out of context.
Then there's the hit on the Sick Mob Man, after which Connor puts his hand over Rocco's mouth, and kisses the back of his hand. Which doesn't even make sense in context, unless you count Rocco'simmediatesilence.
Squick: Other reactions to fangirl shipping listed above.
The hockey arena is a subtle callback to [[Greenly suggesting that their mass execution of the mob bosses take place center ice at a Bruin's game because of how public it will be. It's an homage to the passing of his character, as is the line "Thanks for coming out."
Fanservice: Connor and Murphy get an outdoor shower scene.
Fetish Fuel: Eunice Bloom at the scene of the priest's murder as well as her cowgirl outfit while investigating the penthouse shootout. (Actually, just Eunice Bloom in general.)
Narm: Special Agent Bloom's slightly lisping southern accent sounds just a wee bit like Truman Capote at times.
