Doctor Strange

Marvel released the first trailer for their next movie (after Captain America: Civil War, which comes out next month), and from the little bit they showed, it definitely looks different from the myriad of movies (aesthetically, anyway) they've put out so far. Doctor Strange, starring Benedict Cumberbatch as the titular character, is the first movie in the current Marvel Cinematic Universe to introduce the concept of magic, which is one of the more complex things in the comics. Things having to do with magic usually involve demons, alternate dimensions, reality warping and even multi-universal beings that represent abstract concepts (such as eternity, order and chaos, etc), so it's definitely a bit more out there than Iron Man's tech or super soldier serums. I personally can't wait to see how these things are portrayed in the movie, as the CGI seems to get better with every new Marvel movie. Already I can tell that it's going to at least look a bit different from typical Marvel movies (it looks a lot more like Inception than a superhero film), even if it ends up following the same story formula.
