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.
YMMV for the film Red
Acceptable Targets: In both films, the protagonists usually refrain from killing law enforcement officers and other mooks simply doing their jobs. However, in the sequel, they freely gun down numerous Iranian embassy guards, who are described as hardcore Revolutionary Guard extremists.
Accidental Innuendo: The first film has the tagline, "There's no substitute for experience." They were referring to fighting, but it did costar Helen Mirren...
Crazy Awesome: Boggs, he keeps a grenade launcher in a stuffed pig he carries everywhere; and even uses the grenade launcher as a baseball bat to hit a grenade back at an attacker - and that's before he shoots an RPG round dead-on. Also, his Properly Paranoid streak helps the group anticipate and deal with or escape several encounters.
Foe Yay: Frank and Cooper. Slightly disturbingly, though arguably less foe-ish, Cooper and the elderly archivist.
Frank: Six one, cute hair?
Archivist: Hair was cute!
They could quite easily just be mocking the younger agent, who clearly spends a bit of time in front of the mirror every morning styling his hair.
Reality Is Unrealistic: While the specific example of an unbreakable lock being set next to a very breakable wall may not be a literal example, it's representative of a larger problem government organizations have of doing something extremely competently up to a certain point and then screwing it up with a glaring lack of foresight. One real-life example is a computer that the armed forces designed that was able to withstand absolutely any possible damage, up to and including the location it was in surviving a direct thermonuclear strike... but you couldn't take a drink into the room with it or you might ruin the keyboard.
Complete Monster: Yakushi Kabuto, a Depraved Homosexual who rescues Itachi from execution in order to make him his sex slave, turns out to have been the sadistic guard who almost killed Nagato and brutally beat Sasuke and eventually murders Itachi, possibly to cover up their relationship, possibly just because he's that much of a vicious sicko.
Needs More Love: Has an uncannily low number of reviews on Fanfiction.net for such a good story.
Tear Jerker: Too many to list. Most notably Sasuke being caught with Sakura in her family's basement and being dragged away to the concentration camp, Itachi being betrayed by the doctor he thought he could trust and escaping back to his hideout only to find his sick lover has been murdered and Yahiko's death.
Itachi's death in chapter 21 takes the cake.
Just when you think it's safe, just when you think the story will head in a different path from The Book Thief, just when things are starting to look up again, the bombs drop.
