Nick Fury (Samuel Jackson) gathers this disparate group of six superheroes to battle an invasion by Loki and his alien minions. The group includes: Iron Man, Hawkeye, Black Widow, Thor (who incidentally is Loki’s brother), The Hulk and Captain America. Iron Man (Robert Downey, Jr.) again serves up lots of one liners and comic relief. The director manages to give each superhero character fair time and distinctive roles and personalities. The plot is predictable, but entertaining. Each character is well developed and none are overwhelming. As expected with Disney, the special effects are top flight. It was viewed by this reviewer without the benefit of 3D format.
