I have to say Dr Strange was a fresh and welcome treat. I really, really enjoyed the movie. And not like how I enjoyed GoTG while not knowing the source. I knew who Strange was but never delved into reading his comics. But unlike GoTG I was way more interested in him as a character and his entire mythos. It was nice seeing him develop into someone who will be the "sorcerer supreme" that I knew him as when he mildly appeared in a comic I read.
No 3D for me, I go to the AMC Dolby Atmos theater. That experience is amazing. However I feel because of the visuals maybe this should get a viewing in 3D.
Overall I liked the pacing, writing and jokes. Cumberbach literally looks like he jumped out of the pages of the comic. From the goatee to the subtle grey streaks on the side of his head, i really appreciated the attention to detail.
While I know some may feel the movie was a bit rushed, I rather enjoyed that the movie didn't take too much time on one particular element, be it his background, training, even the final confrontation was well done.
I definitely rank this high on my MCU list.
