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.
Also, Santa Christ. He's either way cool and a fitting part of the special or a God Mode Sue who should never have even existed. Whatever you thought of him before, Kickassia won't change your mind.
Better on DVD: The whole thing is meant to be watched all in one go as a 90-minute film. The orginal idea was to release it in three parts, but it was later changed to six (see Trilogy Creep below). That said, Doug himself has advised that's it's best to either watch the whole thing from start to finish or, failing that, watch parts one and two together, parts three and four together and parts five and six together.
The timing on the music in Part 4 when Ma-Ti yells at The Nostalgia Critic as he exits is perfect!
In Part 5, the Boss Theme from the SNES Batman Returns game becomes a Crowning Music of Funny.
Dude, Not Funny!: Some German fans took issue with the Godwin's Law gag in Part 1. They acknowledged that it wasn't as bad as it could have been (the joke is clearly not about the Nazis themselves, but the Critic's nonsensical use of them as both positive and negative reinforcement and everyone else eagerly going along with it), but still thought it too much in bad taste to be funny.
It would seem they're more upset that the Nazis are brought up because it's one of the low points in Germany's history, rather than anything else, since some of the Jewish posters on the That Guy with the Glasses.com message boards have pointed out that they took no offence to it, and they had more right to be offended by the joke than the Germans. And that's forgetting that at least one of the people actually on screen in that scene is Jewish.
Not just onscreen, but, in a deleted scene, had specific attention drawn to him for a few seconds (hiding a Star of David necklace).
During the hotel scenes, there was a maintenance worker outside the window was referred to as Mexican Spider-Man (A. K. A. Mexican Batman) during Linkara's commentary. During the commentary, Obscurus Lupa said that there was a side-quest where she and Mexican Spider-Man build the fence from Part 2.
Lee's interview with Chris Larios: "You feel beautiful."Well, he is 3-D now.
In one of the bloopers, Benzaie kisses Spoony on the cheek when trying to get him to turn into Dr. Insano.
Idiot Plot: The main source of humor is derived from the fact that pretty much nobody (exceptions being maybe Phelous and The Snob) acts like they have anything resembling common sense.
Jerkass Woobie: Critic, the Jerkass bit more pronounced than normal. The banishment of Cinema Snob gets followed by the sympathy-inducing Big Lipped Alligator Moment of Ma-Ti warning him in Part Four. In Part Five, after being as upset as everyone else with the accidental shooting of Santa Christ, he decides to throw the dead body in the dumpster. And in Part Six, the whole episode is him getting his comeuppance.
And you get to see how ridiculously fucked up he is in the latter half. The guy's clearly insane, but you've got to pity him in some form.
Magnificent Bastard: Fritz von Baugh in part 3. He goes around convincing everyone that they could be better presidents than the Nostalgia Critic as well as making the military distrustful of their leader by planting evidence of possible evil on the Critic's part. This is Lampshaded by the Cinema Snob.
Moral Event Horizon: The Critic's killing of Santa Christ is seen as this by the team, even though he didn't mean to and went to great lengths to try and bring him back. Even Film Brain turns on the Critic after the fact.
Nightmare Fuel: Spoony transforming into Doctor Insano. This picture from the credits illustrating the scene helps add to the creepiness factor.
The Critic revealing what he needed that dynamite for along with his use of the term "Nasty-wasties."
Rescued from the Scrappy Heap: Both Film Brain and Phelous were immensely hated at early points of their review careers. In Kickassia, they are given plenty of screen time and funny moments to encourage people to give them a second chance. Both succeeded.
Rewatch Bonus: After the Critic/CR crossover where the former admitted to being disgustingly self-loathing and insecure, a lot of Critic's behavior here suddenly makes sense. It also has the bonus of adding depth to the Looney Tunes-esque flick, even if it's only with his scenes.
Spiritual Licensee: As admitted by the cast and crew, Kickassia is basically a fully live-action Looney Tunes skit. The initial encounter between Nostalgia Critic and Baugh are even a direct remake of Wile E. Coyote's introduction in his encounters with Bugs Bunny.
Unfortunate Implications: The Critic's speech about Nazis, although the joke was to point out what dumbasses these people are.
The Woobie: Doctor Smith, whose idea of a legion of spiiiders is hated by everyone (except JewWario).
Spoony. Seeing him tense up over the fear of unleashing Insano, how could you not want to give him a hug and tell him it's going to be okay?
Arguably Film Brain. His character was basically a huge Nostalgia Critic fanboy, yet the Critic himself always seemed disinterested in him. Due to his strong dedication to the Critic, the rest of the cast also disliked him because he refused to help overthrow the Critic until the Critic killed perhaps the one person he idolized more: Santa Christ. Sure, he was a Yes Man, but he was such a fan of the Critic, he didn't realize he was being such a brown-noser.
