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: The Joker, starting with his Moral Event Horizon. After finding out Harley was secretly helping the Green Goblin, the Joker shoots her. Later, after tricking the heroes into thinking The Punisher shot him, the Joker leads Harley away as they try to escape. The Joker assures Harley he wasn't going to leave her there to die...and then hits her to the ground, saying this is a much better spot. When he comes back from the dead in Rorsarch and Deadpool 2, he kills a mook who sold him out in a very painful and thankfully offscreen manner, then shoots Rorsarch.
The movie parodies are generally amusing. But repeatedly spiking Spiderman's milkshakes to get him to come up with said parodies is kind of uncomfortable. Batman naturally lampshades this but then also spikes Spiderman's milkshake when he suggests that his new movie might make more than The Dark Knight Rises.
Also might apply to when the guys drugged Alfred in order to "get an authentic British voice" for a Harry Potter trailer spoof. Batman naturally wasn't pleased with that.
The local version of the Green Goblin is just hilarious to watch.
Ever since his introduction, Deadpool has become just as popular, maybe even moreso.
Lars M. Dusseldorf is probably a truer version of this trope, as since their popularity became apparent Deadpool and Gobby have been pushed increasingly to the fore, whereas we can be assured that Lars is not going to take centre stage. But he is very, very awesome.
In the Rorscach & Deadpool Buddy Cop parody, the pair are on the trail of a mysterious crime figure named Joe Palachi, who turns out to be The Joker, and more specifically the humorless 80's one from Frank Miller's The Dark Knight Returns. There are about three layers of brilliance to this, one of which Joe himself admitted to being the reason he picked it:
Firstly, Palachi, whilst being a sort-of common Italian surname, is also a reference to the opera Pagliacci, and the lead character of the same name (it is sometimes called Palachi's Opera). That was a subtle clue as to Joe Palachi's true identity.
Secondly, this is a Watchmen reference and specifically a Rorschach reference, since in the comic Rorschach tells someone about a joke he heard about Pagliacci.
And third, the joke is about how the great clown Pagliacci is utterly depressed and miserable because he has come to view the planet as a Crapsack World, which perfectly reflects the fact that The Joker pretending to be Joe Palachi is the most serious, unfunny Joker ever put to print- turned Up to Eleven when it turns out Darkseid has brainwashed him with the Anti-Life Equation which makes him really believe this:
"Man goes to doctor. Says he's depressed. Says life is harsh and cruel. Says he feels all alone in a threatening world. Doctor says, "Treatment is simple. The great clown Pagliacci is in town tonight. Go see him. That should pick you up." Man bursts into tears. Says, "But doctor... I am Pagliacci.""
Another example is just in the pairing of those two Deadpool is a walking Satire/Parody of comic books antiheroes/anti-villains , whilst Rorschach is a Deconstruction of the Anti-Hero/Anti-villains.
"Funny Aneurysm" Moment: After Spider-Man wakes up from a dream in which his incarnations from both of his movie franchises feud, he tells Batman that The Amazing Spider-Man might outgross The Dark Knight Rises. Even though Spidey's movie made enough money for the studio to greenlight a sequel, it still made about $200 million less than Dark Knight Rises.
Genius Bonus: Deadpool's Trade Snark during the "Rorschach and Deadpool" song (Copy and I'll suuuuuuuue) is made all the funnier when you realise that the backing track (And the melody based off said backing track) is based around "West Precinct Medium", a piece of royalty-free music from Apple's iLife bundle included with most Apple products, which under most circumstances are perfectly legal to use in videos one is making money off of.
So the trailer for the 2011 DC Universe Online premiered and in it a future Lex Luthor traveled back in time to warn the heroes that the world would be destroyed if they didn't stop him. Sound familiar? Hilariously enough, RandomGuy lampshaded this in a recent BlogTV chat:
"Green Lantern vs. The Critics" ended with Deadpool going through the Reynolds-ing as he now has Ryan Reynolds to himself. This becomes much funnier now that Ryan Reynolds has been cast as Conner MacLeod for the upcoming reboot.
"Ways To Screw Up The Avengers Movie" had a running gag of butchering the phrase, "Avengers, assemble!" It would later become revealed that the movie actually threw out the phrase altogether. Said gag ends with Cap saying "Avengers Assemble . . . a Human Centipede!" Come Agents Of Shield, well . . .
Another part of this video was Nick Fury saying In Ways to Screw Up the Avengers Movie "I'm here to talk to you about the Avenger Initative...Howard." And now he's appeared in the after credit scene of Guardians of the Galaxy
In a video where Adam West's Batman and Howard the Duck face off, Batman makes a comment about Marvel Studios preferring talking raccoons to talking ducks. In Guardians of the Galaxy the studio has it both ways

Moral Event Horizon: The Joker, naturally, crosses this in the final episode of "Happy Hour". After finding out Harley was secretly helping the Green Goblin, the Joker shoots her. Later, after tricking the heroes into thinking The Punisher killed him, the Joker leads Harley away as they try to escape. The Joker assures Harley he wasn't going to leave her there to die...and then tosses her aside, saying this is a much better spot.
Selfish Good: Depending on the tone of the vid Iron Man was in. As he puts it, people kind of expect him to be a media whore.
Shallow Parody: The movie trailer parodies sometimes fall into this, usually by copying the trailer and adding jokes based on which character replaced whom.
