Although we're all excited for the series coming up in, like, two years from now; we should take some things into consideration:
1.Nothing will ever be better than the books.
2.The production can't be exactly how the books are as it would make it predictable, boring, and uninspired. Expect changes, ma dawgs. Some people think they should add gods from different mythologies. (It might be fun to see RRP-esque stuff).
3.The movies weren't too bad if you see it as a movie and not a book adaptation. From Screenrant, I hear the Computer Generated Images, (CGI), some stuff with the plot, and the cast was good; but only a mortal can say that stuff was awesome and not an insult.
3b.Still on the movies, all the plot-cuts, holes, edits and other related things were influenced by two things; Time & Budget.
Time: The average movie isn't supposed to be more than two hours and thirty minutes. Imagine having to fit a book you can read for a month in such limited time. Or try seeing yourself watching a six hour movie just because these people wanted to please us.
Budget: Everything works on a budget, from your house to your country to something like this. Sure, they used that much money on a big pile of schist, but look at it this way: you're given a certain amount of money to make the best adaptation since Harry Potter, but when you read the books and see some things as too over-budget, (the Echidna scene, for instance), also considering that a lot of popular child actors are booked, also considering your limited time (once again), you can only spend so much, cut a ton of stuff, andhope it doesn't flop.
That doesn't mean they couldn't have done better, though. But think about it.
3ba. Disney could definitely get those kinds of problems. Especially with Corona crashing economies
4. Let's all hope and pray they don't do what they did with Sadie Sparks.
