An American fantasy action film; A story about a superhuman soldier who is propelled into conflict with his Avengers teammate, Iron Man, over a system of government control over their actions. Collateral damage comes home to roost for the Avengers superhero adventurers. Some agree to being, others do not. It's an interesting, topical story direction and it's a more mature and substantive picture because of it. Compared to the previous films in the series, the fighting sequences have a little more purpose, showing the dynamics of their abilities, and while the set pieces go on too long, they are impressive. Tension reduces because it doesn't convince why the allies are opposing each other with lethal intent. What the producers gain in satisfying their growing and committed audience, viewers unaccustomed to the Marvel Universe films will feel it is overstuffed with characters. All in all, an exhilirating adventure.
