This Iron Man DVD is a "motion comic" from Marvel Knights. They have taken the Extremis comic and turned it into a quasi-animated movie in six episodes. Before you discount this style of animation, note that the artwork is far superior to any of the other Marvel/DC "animated movies" (which all seem to look like slightly better versions of Cartoon Network cartoons) because it utilizes Adi Granov's original artwork with CGI enhancements of most of the tech and action scenes. The animation is fluid, and after only a few minutes you won't even realize you're not watching a fully-animated Marvel movie.
The strength of this DVD is Warren Ellis' storyline, which is more compelling than any recent comic book movie, except for perhaps The Dark Knight and the first Iron Man movie. This motion comic is unpredictable, hard-core, and exciting.
My only complaint about this DVD was N. Ronald Levine, who voiced the character of hippie Sal Kennedy - what a horrible casting choice! The scenes with Levine take you right out of the movie as you roll your eyes at the bad acting. Luckily, he's not in the movie much except for one scene in the middle.
If you're like me, every time you buy one of these Marvel or DC animated movies, you look at the cover art and eagerly hope that the product itself utilizes that same level of artistic expertise, only to discover that it's another Cartoon Network-looking piece of crap. But with Iron Man: Extremis, you finally get to see a full story with top-notch painted animation - and it's worth it!
I'm glad I gave this product a chance...and you will be too.
