The Avengers (Avengers Assemble in the UK) has been hugely successful at the box office, and has generally received positive reviews.
However, Scott wrote in The New York Times that the film's "failures are significant and dispiriting".
Jackson yesterday (May 3) tweeted in response: "#Avengers fans,NY Times critic AO Scott needs a new job! Let's help him find one! One he can ACTUALLY do!"
Another user later tweeted: "Disappointed to hear @SamuelLJackson respond irrationally to negative review of #Avengers. People aren't entitled to their own opinion? :("
Jackson replied: "That is My Opinion! @TheFilmNest & what's irrational about it? They aren't going to fire his jaundiced ass & You & I Know It!"
