I actually went and saw it yesterday.
Had a lot of fun, the same winning Marvel formula they have been using. It did take awhile to get used to Benedict's accent, but it did remind me of Laurie a lot, but that might just because of the doctor scenes.
The mirror new york scene was just breathtaking in 3D.
There is one teeny little thing that bothered me though, very small, but the nerd in me couldn't help but notice. They mention in Winter Soldier that Steven Strange is a target of Project Insight, because he was deemed a "threat" to Hydra, which makes sense if he is the Sorcerer Supreme. I thought they would get around that by having the events of this movie happen earlier then those other films, but at the very start, before his accident, he is in his house and it cuts showing various rewards, all marked "2016". Was Hydra just really scared about how good of a surgeon he was? Maybe he is just deadly with a scalpel! Yikes!
