I've watched Iron Man 3 and it's good. The action scenes are terrific. The plot is somewhat predictable. If the fighting had started from the first second to last, I would have given it 5 stars.
Fans will probably geek out towards the end with all the different Iron Mans. Those Marvel people really know how to milk the series to create action figures.
It's an enjoyable film. The IMAX and 3D are totally unnecessary though.
Below are the Kotobukiya statues for the film.
And the War Machine.
