Breja: Well, they comletely fucked up The Mandarin for one thing. Possibly the coolest Iron Man villain, and an opportunity for a great "magic vs. science" plot and instead they went for a weak twist and a generic Dr Insano villain. There's also Ultron, who they turned into a joke instead of a cold, sinister menace, and pretty much the entire backstory of the Vision is gone. And Thanos' new motivation and goal in Infinity War makes no goddamn sense whatsoever.
I will be honest and admit I have to rewatch Ironman 3. I was barely awake when I saw it so I'm unable to comment on their portrayal of the Mandarin. It's all a blur, might as well have been just the trailer. I don't agree about Ultron. I thought he was a real threat and was consistent in itself. Being an AI he was logic driven to find the simplest path to reach his goal and that was killing all humans.
As for the Vision, I didn't really miss his backstory. He used to be the android Human torch? So what? It didn't matter to him or to anyone around him. It didn't shape any of his actions, his ideals or any plotline surrounding him for decades. It mattered even less to the audience. The character fell into obscurity by the 50s. I've read the comics for decades and never saw a single panel that ties him in with the original Torch. The new origin also ties the creation of Vision to Ultron's actions like the comics did.
Regarding Thanos I admit that it makes no sense, but we haven't seen much. They might surprise us with hidden depths or even some secret motivation that the character was harboring all along. Maybe. Even then, Fox's Xmen movies wouldn't pass this sort of analysis unscathed either.
