This the fourth part in the animated film series! After Ultimate Avengers, Ultimate Avengers 2: Rise of the Panther and Iron Man this is one great addition. From these four movies I enjoyed this one the best! Why? Because I didn't know much about Dr. Strange. It is really fun to learn more about this super hero. (I remember seeing him in a Spiderman comic and that he was specialized in the supernatural and magic! That was it.) This movie does a hell of a job in showing who he is and what he is capable of. Of course the length of the movie didn't allow further characterization or lore surrounding the character. But we learn enough in an incredibly fast pace. Personally I didn't want this movie to end. I loved every minute of it. Because of the magic and mysticism that surrounds this marvel hero the visual effects are very impressive and beautiful. But what stuck me the most was the attention to the psyche of the main character Strange. You'll be witness of a big change in personality. This character development is not something we see often in cartoons about super heroes. Even these superheroes have human problems to deal with. They are not perfect and are just as flawed as we are. That is one of the main reasons why I love Marvel. Doctor. In this case it is even more interesting since Strange really has no desire to be a hero. He basically gets thrown into an adventure of a lifetime because he wants to continue being the best in what he does. That already makes him quite the character. Strange is still the best in this series of animated marvel movies and it makes me wonder why they haven't been able to approach the later ones with the same sophistication and finesse.
Definitely one to check out if you haven't done so by now.
