This movie has an excellent (if not perfect) blend of comedy, action, & a little suspense. The sarcasm Stark (main character) uses is excellent. The personality his lab robots have and quirky friendship they share is a hoot. The invention process of the suit is extremely funny (once you see the movie, note the part about starting out at 10% thrust). As a hero, in the comic book sense, he is unconventional at best. Most heroes have a mild mannered personality. He does not at all. The action is definitely a 5 for 5. Lots of explosions and destruction. Good hero kicking bad guy butt action. The suspense is on the light side, but they used as much as possible without destroying the plot line. The villain is hidden very well until 2/3s into the movie. Basically this is one of the few I will be buying. If you don't have Blue Ray, get a Blue Ray, player, HD LCD TV, and this movie.
