There's nothing wrong with having an opinion but not being able to elaborate on it doesn't give it any substance.
Hell, I don't think like Potter as a story, movie, book whatever but even I enjoyed the rides and even if I didn't, I can certainly appreciate the money that it has pumped into the parks and allowed the to build like never before. If Potter didn't happen, I highly doubt there would be all the new hotels and a new resort on the horizon.
