There was virtually no way “The Avengers: Age of Ultron” could live up to the hype created by the Marvel Cinematic Machine. Expectations were astronomically high. “Ultron” was not only expected to deliver a solid story crammed full of enough Joss Whedon puns to fill a book, but to also set the wheels in motion for THREE other films.
No mere mortal movie could deliver on that. Also, I agree with Honest Trailers: We kinda broke Joss Whedon, you guys.
