Spare me the talking point that Disney is "freaked" by the success of Potter. It has been proven WDW benefits from the success of Universal Orlando. It brought people to Orlando that would not have been there anyway and Disney benefitted.
I will tell you who is showing signs of panic and that is Uni as evidenced by there recent approval to expand Potter. I am sure they had hoped to ride the phase 1 of Potter a bit further. But the buzz has already diminished as evidenced by decreased wait times.
I have not experienced FJ, don't need to. I have read numerous reviews from people I know are not trolling on behalf of Universal. And even the most rabid fanboys can't disguise the undercurrent of dissappointment. I am not saying it is not great as it likely is but for the vast majority the hype could not equal expectations. Marketing can be a two-edged sword.
I will not revisit the Orlando area until they add enough new content. I have too many other commitments to be able to go to Orlando area regularly. But I have been to Universal several times and have experienced everything except FJ and after.
Again, I read tons of reviews and trip reports and FJ may be the most advanced theme park experience ever but it still lacks that special secret recipe WDI keeps locked in the vault.
When more that one person whom I respect claims to love FJ but that they still think Spiderman is a better experience at Universal, then that is all I need to know. As for me. I will stick with the Haunted Mansion. It has all the ingredients. Created by people who understood committment and have/had a depth of character that is rarely found today. And it shows in the final product.
You and others can rant and rave about FJ all day but you can't change this fact no matter how much you would like to.
