- Alternative Character Interpretation: Is Thor really a loving father who just wanted to teach his daughter a lesson in humility and had no option but to return to rule Asgard after Odin's death, or a cowardly slacker dead beat dad with insanity issues and a possibly cruel sense of humor?
- Complete Monster: Ultron is an android, built by Tony Stark to bring order to the world. But Ultron decided that the best way to bring order was to be the one giving orders. To this end he conquers the Earth, killing most of the superheroes in process. After 12 years, during which time Ultron conquered half of the planet, killing millions and driving the survivors underground, he locates Iron Man hiding out in a base in the Arctic. Smashing his way in, he confronts the children, now teenagers, and attempts to kill them for being "potential threats". The kids escape while Ultron beats down Iron Man, at which point he captures and proceeds to torture him for information regarding the kids.
- Evil Is Cool: Ultron.
- Hilarious in Hindsight: While not funny per se, Tony Stark being the creator of Ultron becomes this when one looks at Avengers: Age of Ultron, which also had Tony Stark being the creator of Ultron.
- Idiot Plot: The Hulk could have solved the plot before it even began but didn't because he, or the people who refused to force him into the fight before hand, are either selfish or idiots. All of Hulk's friends are dead, their children are in danger of dying, and humanity is being tormented by a crazy robot, and he does nothing to help, despite being able to defeat Ultron so easily it's pathetic. He seems afraid of turning into a monster, but apparently that fear is more important than the lives of millions! If that isn't enough, the kids get him to fight rather easily by pissing him off, why didn't Tony or one of the other Avengers go to him before the situation got so bad and force him into it? Sure they have to deal with the Hulk, but at least that would have saved countless lives!
- Narm Charm: Thor and Torunn's little reunion at the end.
- They Wasted a Perfectly Good Character: Thor, who was pretty much forced to sit out the entire film for no better reason than he didn't have a big movie in 2008 while Iron Man and the Hulk did.
- Unintentionally Unsympathetic: The film explains that Thor left Torunn on Earth so she would learn the same lesson he did, but it completely ignores that Thor only needed to learn it that way because his own father failed to instill it while he was growing up and went for the tough love approach to get it through. Thor makes no attempt to teach her at all and just figures she'll learn it on her own, which makes him come off as an amazingly lazy father. After all, it's not like Odin didn't have the time to raise Thor, and surely Thor could at least try given he has some understanding of where Odin's parenting style was lacking.
- What an Idiot!:
- James Rogers. He ends up activating the Iron Avengers and giving away their location to Ultron all based on the (not quite plausible) possibility that the robots had been programmed with the exact memories and personalities of the original Avengers, hoping that at least this was the case for his dad's robot.
- All the kid heroes have moments of this. Which makes some sense because they're, you know, kids.
