From my own experience, I can tell that casual fans are the kind of fans that experience Star Wars in the best possible way. When you are overly attached and overly obsessed with Star Wars, you have nothing but constant arguments and continuous headaches, you always find something to criticize, and the way you experience Star Wars is not as relaxed as it should be. On the other hand, when you are a more casual fan who just wants to enjoy Star Wars and doesn’t care very much about anything outside of the films, you really have the best experience because you have a more relaxed approach to the whole thing. Sure, you can still dislike some of the movies, but you will have a more relaxed approach in general, because your dislike will not go beyond the simple “I don’t like this, this and that”, without carrying your sentiment over time as if it was an obsession, indeed, and without being frustrated for the rest of your life because things didn’t go the way you wanted to.
