Interesting. Well, if being a "true EC fan" means grumbling over a clownfish and no longer enjoying an entire pavilion, I'd say I'm proud to be a "fake EC fan," since at least I am enjoying every moment of my time there!
As a Pixar fan, I enjoyed everything about the Nemo additions - from the adorable queue to the effects throughout the ride. As an elementary teacher, I can appreciate how they've tried to pique children's curiosity in oceans and marine life via a recognizable character. I sincerely do not believe the pavilion has lost any of its integrity - It's simply been re-themed.
