Although audiences have seen a lot of concepts and inclusions in the Marvel Cinematic Universe that are a far cry from real world science, the fact is that the whole thing has been based on science so far. Even the powers of Asgardians and related "mythical" characters have been presented as science that the real world simply doesn't understand. However, the introduction of Doctor Strange is set to stretch the boundaries of the Marvel Cinematic Universe into the realms of the supernatural. As exciting as it is, this is a huge risk, as some people might see the idea of demons, spirits and spells a step too far in terms of silliness for this particular universe. Here's hoping that - like most things they've done so far - Marvel Studios get it right.
