I was hugely impressed with the first Iron Man film, the mix of action, humour, quality sound and superb effects made it possibly the best superhero genre film out there. Sadly, as if often the case, this sequal doesn't live up to expectation.
The film is entertaining, with once again some very impressive effects and sound (5.1 is outstanding here!), but the script and casting could have been better. The storyline is paper thin, with the lack of building new charatchers or adding dept to those already in place. Don Cheadle, despite being a fine actor is poorly cast in this and GP might as well not have bothered reading the script for Pepper Potts, as she much have to only deliver a dozen or so lines.
Despit all this, it is still better than 75% of other films in the market and will provide you with some mindless entertainment, perfect for a Saturday night in or a lazy Sunday. I just hope that their saving some of the better work for Thor/Captain American and the Avengers film
