Portals

Back to Thor: The Dark World "“ if Guardians of the Galaxy is inventive in the way the heroes distracted the villain, this movie has the most special fight scene in the MCU, in the sense that it doesn't take place just on Earth.

Basically, Thor and Malekith fight wherever the portals lead them. And since the villain is infused with the power of an Infinity Stone, the hero has a bit too much on his hands. I really don't see him winning without the help of his sidekicks (or whatever they may be).

Anyway, even if it isn't the best of all superhero movies, this MCU flick has one of the best openings, as well as one of the best third act fight scenes. So, with the worst trilogy of the lot (hopefully Thor: Ragnarok will prove me wrong), Thor at least has that.
