Perhaps there is a distinction between fans and "hardcore fans."
Heck we fans can't even agree on everything. Some of us love the EU for example, others hate it. Some love the prequels, others hate them. Some love the Special Editions, others hate them, etc. And we're all fans! There's different levels of fandom. And some of the people who only like the movies are as hardcore as the people who read every book and memorize it.
