What do you mean, Thor The Dark World is not a Star Wars movie? It has cool shiny sword fights, cool starships flying around, people having to disable a shield by a well-placed strike from within, a prison break and it stars a blonde protagonist, Natalie Portman and a cool dude with a roguish smile that will definitively be the fan favorite.! It's clearly a Star Wars movie! And a good one!
It's really worth it.
As for the deleted scene the director wasn't a fan off - don,t worry. It just has with the fact that this movie is Star Wars, and that scene is Farscape.
