'Iron Man 3' Early Buzz: London Likes Shane Black's Marvel Sequel

Iron Man 3 screened for press in London last night, and while reviews remain embargoed, Twitter reactions were given the OK by the studio. And so now we've got the first slate of responses to Shane Black's film featuring Robert Downey, Jr. in his fourth turn as Marvel's armored hero.

They're not the most measured group of reactions, and as with any collection of first-blush responses to a big film the first Twitter posts only hint at what we might find in the movie. But if you're looking for a general "is it good or not?" answer, you might get an idea below.

If you want to know even more about what doesn't happen in the film before seeing it (though I'm not sure why you'd want that) then check out What Culture's list of ten things that don't happen in the film.

Iron Man 3, starring Robert Downey Jr., Gwyneth Paltrow, Don Cheadle, Guy Pearce, Rebecca Hall, Stephanie Szostak, James Badge Dale, Jon Favreau, and Ben Kingsley, opens on May 3, 2013.

Marvel Studios' "Iron Man 3" pits brash-but-brilliant industrialist Tony Stark/Iron Man against an enemy whose reach knows no bounds. When Stark finds his personal world destroyed at his enemy's hands, he embarks on a harrowing quest to find those responsible. This journey, at every turn, will test his mettle. With his back against the wall, Stark is left to survive by his own devices, relying on his ingenuity and instincts to protect those closest to him. As he fights his way back, Stark discovers the answer to the question that has secretly haunted him: does the man make the suit or does the suit make the man?
