Whedon reused that same "gag" in
Justice League too, if it wasn't already obvious that he was a creep:

Age Of Ultron itself, I'm not a huge MCU fan, but I actually enjoyed it on the whole, moreso than the original
Avengers even, which, for all the hype it got as the first big "when worlds collide" moment for that franchise, still felt like a very generic, forgettable Superhero movie to me.
Ultron, on the other hand, at least had some actual style & personalty to it, which this guy goes into detail on here...
...and, while it's hardly a great movie, since it still feels like a fundamentally disposable corporate product, at least it was a reasonably enjoyable one for me.
