Like most anime animation, the visuals are stiff and boring with bizarre character expressions.
The story is absolute garbage. Essentially, some unknown villain attacks a space launch and in the process kills a key character, and so Iron Man decides he wants to track down and stop said villain - but for some unexplained reason, Nick Fury/Shield don't want Iron Man pursuing the villain and so they send Hawkeye and Black Widow to stop him. At some point, Iron Man meets up with Punisher, but honestly, I still don't really understand why, and it's such a short lived scene that I imagine it was only added to so they could say Punisher was in the movie.
The villain himself is such a chump - viewers will end up hating him because he's just so annoying rather than villainous. And when he starts spouting off quotes from the bible, I just about turned it off - how cliche can you get. Boring!
This movie has zero redeeming value. The action is dull, the story is terrible, the villain is annoying, the animation is awful.
