This may be a perverse response, but I enjoyed “Age of Ultron” more than its predecessor, despite the fact that it’s almost exactly the same thing. This was probably a result of adjusting my expectations: I wasn’t sitting there waiting for Whedon to revolutionize the genre, or to turn an overdetermined comic-book movie into a Noel Coward comedy. He delivers a clean and capable entertainment, with a handful of distinctive flourishes stuck to the margins. Whedon does well with the darker edges of Robert Downey Jr.’s Tony Stark (aka Iron Man), an arrogant tech genius whose degree of repentance for his war-criminal past is always ambiguous. He adds sparkling notes of screwball comedy, and even tragedy, to the incipient romance between Scarlett Johansson’s Black Widow and Mark Ruffalo’s Dr. Bruce Banner (who, like so many lovable men, has a big, green, ugly side).
