Can't wait for Dr.Strange!
However, my expectations aren't huge when it comes to the villain.
Marvel makes great movies, and have been on a roll lately. Their villains however, are generic as hell. They work for the plot, but are overall very forgettable.
Mads Mikkelsen is great though, so it might be good!
Villains in the MCU:
Great: Loki, Winter Soldier
Ok: Ultron, Obadiah Stane, Red Skull, Zemo
Forgettable: Malekith, Yellowjacket, Abomination, Ronan, Killian, Alexander Pierce
Stupid: The fake Mandarin, Whiplash (where's my burd)
The Marvel Tv-shows are doing it right though! Fisk and Killgrave are right next to Loki in terms of awesomeness!
