Yeah i was actually quite disappointed by Ultron, or maybe i just had too much hype and expected alot more from the movie after watching the trailers.
It seemed like a quick build, and after that Ultron himself didnt seem all that menacing.
He talked tough, but didnt really do much until he was in the jet and killed/injured QuickSilver.
Heck Cap was holding his own against Ultron Prime.....Thor would have made mincemeat of Prime Ultron.
Also, why was it that Ultrons Vibranium Armor got decked so easily....isnt MCU Vibranium similar to 616 Vibranium?
Nonetheless, beyond Ultron not being as menacing as i would have liked, the movie was pretty good.
