I have to disagree with the majority that are questioning Fantastic Beasts.
Maybe its just my opinion, and maybe I would get a far better understanding of the popularity with the current Wizarding World from your responses to the following question.
What makes the Harry Potter World special to you?
Is it really the characters? Its nice to have a host you know, but are the characters really that special in the rides? I haven't experienced Hagrid's yet, and I imagined that hearing his narration is probably a cherry on top of the ice cream, but on the other rides do the characters really add anything?
For me, getting the feeling of riding on a broom, dealing with dragons, being attacked by dementors/spiders/trolls is really what makes the rides. The really cool treats, spell casting areas, and full immersion into another world is what makes the area. I also like how tight the area feels, provides better immersion. I can't think of once where Harry Potter, and his gang really made me feel wow this ride would suck if they were not in it. Maybe when you are following Harry through the quidditch area in FJ, but even then its the flying part that's cool.
I love Harry Potter, but I really think its the immersion that really gets people interested. I have met so many people that really didn't care for the Harry Potter movies, especially adult men, but have told me they love the lands.
Star Wars has so much controversy built around it that die-hard fans would have been very critical of it not representing the originals. I don't think that there is that much dislike for Beasts. I think people still like Kowalski and Newt enough to not mind them on the rides. The Wizarding World is enough to provide enough enjoyment.
This is why my list of the lands that will surprise me the most will be
1. Fantastic Beasts
2. HTTYD
3. Classic Monsters
4. Nintendo
Nintendo will be great, but I think it will be what I am already expecting. I feel like my excitement and expectations for MOnsters is so high that I think I will be let down. Love HTTYD movies, and can't see a way how they could ruin it.
