Action packed from start to finish. Robert Downey Jr. finally gets the opportunity to put his angst, demons and condescention into the right role and turn it into Box Office gold. Well written dialogue adds humor and sarcasm which Downey executes wryly. Jeff Bridges is perfect as the true villain and Gwyneth Paltrow makes a convincing sensitive 'gal friday'. There are also several other 'also starring' roles that were well written, cast and played. I was exhausted from a long work day when I walked into the movie...left the theater positively jacked up on adrenaline. If this movie doesn't thrill you, check your pulse, you may be dead. Easily going to be one of the biggest of the Summer!!!
