The story itself is fairly basic and tells the story of an egotistical doctor who loses the ability to operate after an accident and, while trying to heal himself, ends up in the world of magic. It is part a movie about him training and learning to use his powers and part battling the forces of darkness and the story's main villain (played by Mads Mikkelsen). The supporting cast comprises Rachel McAdams, Chiwetel Ejiofor, Tilda Swinton, and Benedict Wong. They all do very well in their respective roles. There are end-credit sequences, as you would expect. One that sets up one of the next MCU movies and one that is likely the beginning of the storyline for the Doctor Strange sequel.
For those who get the blu-ray, it looks and sounds great. It has the best visual effects of all the Marvel Movies so far, and they come out on blu-ray. For extras, there are about an hour of various making-of and behind-the-scenes features, a gag reel, a short comedy feature with Thor, and a commentary track from the director. Very good for what is there.
All in all, the movie is well-written and acted. It does not do too much, just setting up the character and giving him a good introductory storyline to work with. It is visually stunning but tells a good enough story that the special effects do not dominate the entire film. If you have collected the other movies and/or shows up to this point, chances are you will buy this anyway, but if you only have some of them, this is definitely worth adding to your collection.
