I found the whole Ultron stuff pretty bewildering myself. Tony casually tosses out that JARVIS isn't a smart or real enough AI to protect the planet in his discussion with Banner and I'm all, huh? Could he elaborate, please? Because JARVIS seems pretty damn smart to me, able to crack wise and pilot multiple suits at once. And then it turns out he's got a few other AIs on hand, ready to plug in and fly with?
Then we get your standard AI-gone-wrong trope with Ultron deciding to kill everyone, which, yawn, okay, but then he muddies the waters by talking about how humanity needs to evolve, and I'm going, well, which is it? Pick one! Does he intend to eliminate the chaff from humanity's wheat, or clear the way for enhanced and/or Inhuman individuals, or just simply kill everyone? If the idea is he's too young and overwhelmed with sentience to think clearly, maybe it was a mistake for the quintessentially self-assured Spader to voice him; maybe a child's voice would have been more appropriate and scarier.
Then the Widow/Banner flirtation... well, that didn't work for me in the slightest, either. Just don't see a hardened and haunted warrior like her falling for such a mild-mannered dude. Then again, I've yet to see any evidence that Ruffalo's Hulk really is "always angry" as he says. Norton had an inherently haunted look and had reasons to be pissed, reasons which are still more or less canon, but if he's still irked about, say, being separated from Betty, it would have been nice to have mentioned that. Like Locutus said, maybe the deleted scenes will help there. In the meantime, I agree with his
