BBs ''beginning'' was a complete ripoff from Doctor Strange's origin. So much so it rubbed me the wrong way.
That's part of why I liked Begins, I think. But old mystical mentor guy deep in the mountains isn't enough to qualify as complete ripoff imo.
I don't know how they are going to play Strange, but the thing with him is that he has to believe, because it is his only chance, but he can't, yet he'll do whatever it takes. He is broken and while looking to put himself together again opens his mind and answers the call.
Batman is just really a lost puppy who is too rich and famous to not be bailed out. He's given a way out not realizing he's being manipulated. Sure, he grows and gains some insight, remembers his morals and flees to do his own thing, but I think they play out different enough.
I really hope Strange goes all out on visuals tho. If there is one Marvel movie that needs it, this is it.
