Doctor Strange: 9 Reasons It's The Weirdest Marvel Movie Ever

Although we've witnessed other worlds before in the Marvel Cinematic Universe, Doctor Strange takes that to another level. Building on the idea of alternate dimensions seeded in Ant-Man, here we see a variety of different dimensions only accessible to those who've trained for it.

As outlined, the Avengers protect the world from physical threats, and the masters protect the world from metaphysical ones. During the film, we see Strange in the astral plane, the mirror dimension, and the Dark Dimension.

Playing around with the cosmos and multiverses is something that's been expected for a while in the MCU, and Doctor Strange was always likely to be the movie that made the leap.

Each of them bring something fairly unique: the astral dimension allows the characters to leave their physical bodies behind, and fight on another plane; the mirror dimension traps them in a world quite like our own, but where they can't cause damage; and the Dark Dimension, of course, is the really powerful one, where the mysterious beings and powerful foes reside, hoping one day to enter Earth and take it for their own.

With Thor and Guardians of the Galaxy, the MCU has branched out beyond Earth, but never quite like this before. The ideas are big and strange, and the otherworldly visuals serve to really compound the weirdness.
