If you've seen the Iron Man movie then you'll already know that it's awesome... possibly one of the best superhero movies in recent years. The game follows the film pretty closely in all respects except quality.
Graphically, the Wii version resembles a four year old's attempt at making a LEGO robot before getting bored and throwing it in the mud. And then stamping on it. And then leaving it there so a fox can take a dump on it.
As if it didn't look bad enough, the game engine itself is appalling. Enemies explode in such a primitive manner its like you're watching a 1970s budget film, objects disappear before your very eyes and wooden structures that can be blown up one second, remain intact the next. Quite simply, it's a complete shambles of a game.
