Ok, so the stateside critics are beginning to add their two cents to the slew of fanfare following Avengers: Age of Ultron -giving us a more complete spread of reviews for Joss Whedon's superhero sequel. In Marvel-Disney's latest film - which has already done massive business overseas - Tony Stark jumpstarts a dormant peacekeeping program to spark Iron Man, Captain America, Thor, The Incredible Hulk, Black Widow and Hawkeye back into action.

Age of UltronThe Avengers: Age of Ultron has scored pretty solid reviews from critics

"Joss Whedon shows his considerable gifts for multicharacter air traffic control in a massive 3-D spectacle while demonstrating reserves of insouciance," said Liam Lacey of the Globe and Mail.

"Whedon gets the elastic physical reality of comic books, and he knows how to frame a shot as though it were a splash panel come to life... But by the fifth digital showdown, the endless CGI spectacle begins to feel a little numbing," said A.A Dowd of the A.V Club.

"Ultron is slyly funny. And it manages to balance this sort of comedy (I hooted when the Hulk listens to Maria Callas on headphones) with the tendency towards the sort of whacko-labyrinthine operatic complexity inherent in comic books," wrote Antonia Quirke of the Financial Times.

"Age of Ultron, then, shows what happens when an unstoppable force (Joss Whedon's imagination) meets an immovable object (the Disney/Marvel behemoth)," said Dana Stevens of Slate.com.

"Joss Whedon sets up the future of the Avengers for the Russo Brothers, but this is no longer exciting. It's exhausting," said Justin Gerber of Consequence of Sound.

Avengers: Age of Ultron hits theaters in the U.S on May 1.
