I feel like Fantastic Beasts would have done better if Rowling hadn't been so outspoken

(personally I think it was a better story)

I doubt that Rowling’s political beliefs had a sizable impact on the film’s box office. The problem was that Rowling was trying to write a movie like she writes a novel. There was way too much going on to fit into a 2 hour movie. And a lot of what was there just didn’t work.

In my opinion, they should've divided the Order of the Phoenix film instead of the Deathly hallows, or both, so it's more interesting for those who haven't read the books

If they were going to divide any of the other films, it should have been Goblet of Fire.

That one too. It was useless that Barty Sent had discovered his son's identity just because of a gesture that wasn't in the book.

That writing it like a novel stuff is kind of why I liked them... People keep saying they're sick of movies all being the same and then complain when they're different. Bleh.

Like The Flash

There’s nothing wrong with being different. A movie that feels like a novel isn’t inherently a bad thing. But, movies have limitations that novels don’t have. When JK writes a novel, she can make it as long as it needs to be to tell the story. For a movie, the studio isn’t going to let her go longer than 2 hours. She tries to fill the movies with as many subplots as she would put in a novel, but there isn’t enough time to do any of them justice in a movie. That means that none of the plots end up working well or making any sense, and the whole thing ends up being a mess.

As for The Flash, I’m not going to go too much into that on a Harry Potter fandom. Its problem wasn’t that it was different from other superhero movies. Its problem was just that it sucked.

The Flash was just too long for me so I ended up falling asleep in it, otherwise I actually liked it

I meant Barty Snr 😅
