It's looks okay. Definitely a different feeling from other Marvel movies as hey now introduce the concept of magic into the universe.
That was the big change in the comics as well: a hero that brought an element of magic and mysticism to the comic's universe.. When it was first written, Marvel was a little worried since it deviated from the rest of the Marvel universe, but actually did well in the market. Since the comic involved the mystic, the artist used a lot of vivid colors and surrealistic landscapes. Since these comics started in the early 60s, this artistry is actually viewed by many historians as being prescient of the counter-culture revolution in the later 60s and 70s with its fascination of Eastern mysticism and psychedelic influences.
As for the movie itself, I think they'll get away from the hippie ideas from the 60s and 70s, bringing it more up-to-date with its real-world references. I think Benedict Cumberbatch (I know one of these times I'm gonna call him "Cummerbund" by accident) was an excellent choice as actor. His British accent, esp. when depicted in NYC, will aid to the image of Dr. Strange as being an egotistical neurosurgeon snob, giving more credence to the path that the character follows following his crippling accident. I also have enjoy Cumberbatch's other roles, esp. as Sherlock Holmes in the BBC series.
It'll be interesting to see if Marvel will continue using the character in future movies... Will the Marvel movie universe story-arc go into Dr. Strange as being a part of the "new avengers" and Illuminati to save the world from itself from a parallel universe? Since we have already seen certain concepts and characters that lead to this story (esp. the references to the Infinity Gems), I'm thinking that this might very well be the case, as a way to bring together the characters from the Avengers, X-Men, and Guardians of the Galaxy all together.
