I do not think Ultron is gone. But besides that, I loved his presence and portrayal. I've always had a fondness for the utterly psychopathic villain who thinks he's doing right, is charismatic, and just plows forward with a cheerful malevolence. Spader is brilliant at that, and I have hopes that Ultron will return, having learned from his first outing, and being more cold and relentless -- and harder to defeat -- than this time. Good villains have arcs, too. I particularly hope Jocasta comes into play as the "bride of Ultron" she was in the comics...
The B-team ending wasn't horrible... my biggest heartache is always with War Machine. As cool as the armor is, the Iron Man sequels have put a very bad taste in my mouth for the Rhodey character. Mainly because of Cheadle, but also because he has no depth. He's borderline comic relief that stands in the shadow of Stark's greatness. The only reason he is War Machine is because he stole the armor. He didn't build it. He's a tool of the government. I assume by IM3 Tony built Rhodey another suit, so maybe that "stole it" statement doesn't hold much water.
Enh. Rhodey kinda fell into the armor in the comics, too. He was Tony's friend, was authorized to wear the armor after a certain point, filled in as Iron Man to help maintain the secret identity or when Tony was incapacitated, etc. As in the movies, he and Tony had fallings-out and reconciliations, and it was during one of those icy periods that Rhodey took a set of Iron Man armor and turned it into War Machine. This happened, ironically, while the West Coast Avengers were around -- the in-universe "B-team" that got no respect and had to constantly fight to get taken seriously. I loved the final scene of the film for that very reason. "Hey!" I said to myself in the theater, "It's the West Coast Avengers!" More or less. In the comics, it was Hawkeye who formed the team, not Cap, but still...
And speaking of... I think Hawkeye is
the single most under-appreciated MCU character. From what we've gotten so far from all these films:
• Coulson, Hill, and Barton are the S.H.I.E.L.D. agents with whom Fury has had th elongest working relationships and the closest ties (Hill moreso after the first Avengers film).
• Of those, Barton was the black-ops agent sent to eliminate the Black Widow, and not only did he decide to recruit her instead,
he was able to countermand his mission objective and overrule Fury.
• Barton was the black-ops agent-on-scene where S.H.I.E.L.D. was studying Thor's hammer.
• Barton was the black-ops agent-on-scene where S.H.I.E.L.D. was studying the Tesseract -- and pointed out to Fury somethign no one else had realized, that it might be being activated from the other side.
• He was the one member of the team who got the drop on Wanda and was
not taken out by her.
• He was the only one involved in the events of AOU who knew how -- and when -- to contact Fury.
I am honestly a lot more impressed by the MCU Hawkeye than the comics Hawkeye.
