I think the basic problem is that some people want to belong to the group that have known and liked Star Wars from the beginning. By enhancing the effects and thereby making the sequels more accessible to new audiences, those conservative people suddenly don´t feel so special anymore since Star Wars is suddenly also liked by new people who haven´t known it since the beginning.
That´s actually the only reasonable explanation for the conservative and unreasonable attitude of these people who don´t understand that Star Wars is ultimately a six part Saga.
