Avengers: Age Of Ultron - 10 Plotholes That Almost Ruin It

2. Ultron Having Tony Stark's Personality Doesn't Actually Make Sense

The idea that Ultron picks up Tony Stark's personality quirks and his failings is a romantic one and appeals on a couple of levels. Obviously it allows James Spader to do his thing - turning his appearance into an actual performance, rather than just a reading - and it also brings up the idea of Stark's personality flaws being responsible for his rash behaviour.

And of course it also introduces Ultron's compulsion to "improve" himself and create Vision as his idea of what perfection looks like.

But while some complaints about Ultron's personality will pick up on things like him not knowing the word for children when he's basically main-lining the Internet constantly, there's a far more fundamental issue with it.

Tony Stark never actually programmes anything of himself into Ultron. He is actually created by accident, under JARVIS' vague supervision, and it's not as if Stark plugs himself into the mainframe the way Ultron does for Vision.

Plus, if his personality quirks were merely an inherent mark of the creator, why is there nothing of Banner in there? And how come JARVIS is such a pleasant, well-mannered creation?
