It seemed that the superhero movies were following one of two trends; either they were getting darker or they were getting stupider...until this was released. No one new much about Iron Man but it blew their minds, and for a good reason. Funny and likable, Iron Man feels almost like a reason for Downey Jr. to mess around with his alter ego as he fits the part perfectly. In fact, the movie could just be Stark and his suit of armor messing around and it would still have been 100% enjoyable.
Which brings us onto the plot, or lack of, and the action. As mentioned the plot is missing and is riddled with holes but you find yourself not caring too much because Tony Stark is having a good time and so are you. Also what surprised me at the end of the movie was that for an action film, there really wasn't very much action but at the same time I couldn't have cared less. The film was well paced and well scripted, it had a terrific lead actor so what more could you want.
