I saw it at the late 3D showing last night and it was a blast. It's not as action packed -- or at least not in the same way -- as some of the Marvel outings but it had good flavor, excellent acting from the majority of the cast, and the scope of the images were amazing.
If you worry about God wizards in games, think about having to deal with what some of these guys are doing.
Not spoiling much here, but the style that the magicians use to create spells and combat each other in many places more resembles martial characters than magicians. The trailers don't show as much of that as is in the movie; there is a great deal of hand to hand and enchanted weapon combat.
One thing often forgotten is that Dr. Strange is the Master of the Mystic and Martial Arts. XD Saw it myself earlier today, and I definitely enjoyed it, although it felt like more of a setup for other movies than most in the MCU.
