I love the Harry Potter movies and books. I didn't like the first FB movie and then having to watch the second one after not caring for the first one was rough. That said, I am very excited about the upcoming Dumbledore and Grindlewald fight. I was always intrigued by Dumbledore's history as written in the books. Although I didn't care for the movies, I want the Wizarding Land at Epic Universe to stay FB related. There is enough Harry Potter at Universal! I would be okay with MOM at Universal Studios, but I would really dislike another London at Epic Universe. Jumping to MOM on a ride would be ok.
People forget that there was a 100 million drop in gross from Sorcerer's Stone to Chamber of Secrets and then another 100 million drop to Prisoner of Azkaban. There is also less than a 100 million difference between Prisoner of Azkaban and the second FB movie. Harry Potter movies have shown that just because there is a drop in the second film doesn't mean the later films can't outperform.
