They're getting bashed because the execution of the entire project was botched. How do you open the first major project in the Magic Kingdom in over 20 years over the course of 3 years! It's a cheap move to drag out one land and pinch your customers wallet for the least amount given forth. What if Universal opened phase 1 of Potter with just the FJ and DC open? People come to see the opening of the The Wizarding World and once they show up they have to walk through all of Hogsmeade under construction. Oh btw now that we have your money we will let you know that it's only half way done. Come back next year and give us more money to see the rest of what you should of seen today. And don't say it's ok because they announced the Dwarves open in 2014. The general public had no idea that half of the project was still behind fences when they held there grand opening. It was a terrible move and there customer service took a hit.
But then again that's the difference between Universal and Disney today. Here is a direct example of how Disney and Universal are treating there new lands. And for those who don't think there are actually 5 planned opening phases of New Fantasyland I assure you I'm right. It was planned like this from day 1.
