Not being any kind of Star Wars expert, I can't comment on this specifically - but it's a tendency that I have observed in other popular entertainment communities and fan bases; many people seem to equate being critical with being knowledgeable. If you simply say, "That was great, I loved it!" they will sneer and dismiss you as a mindless fanboy. If something about the latest film, t.v. season or series novel doesn't strike them as being exactly what they wanted to see, done in exactly the way they expected to see it done, they will find a way to dissect the thing sixteen ways and try to make it appear flawed from every angle. You can be a true fan, even a fanatical one, and still maintain that childlike wonder and enjoyment at seeing your dreams and fantasies flashed up on a big screen (or a small one), alive and in color.
