Iron Man 2 trailers were impressive but had fears.Most of the sequels lets us down........But IM2 didn't.Introduction of Don Cheadle as Rhodes,Mickey Rourke as Ivan Vanko,Scarlett Johanson as Natasha Romanoff & Samuel L jackson as Nick Fury were the best.........As in Iron Man Robert Downey Jr gave a stunning performance............The special effects,the story,the synchronisation,the direction........were at the best.......We always expect a lot from a sequel............But most of the sequels for an action packed sci-fi gives importance to action and special effects not to the story..................This movie is 1 hell of a ride..........
