Iron Man 2 fails in every aspect where its predecessor, the 2008's Iron Man, greatly excelled. The plot is basically the same like in the first one but even simpler, where the villain holds an increasing grudge against the hero that ends up being solved when they face off against each other at the end of the film. The only thing that saves it from being a mediocre mess is the ability of the main actors to make it feel alive and entertaining.
