I will respectfully say this was a hot take that needed time to be thought out more thoroughly.

All that has to be done is respect the lore and everyone makes their money.

"They need to be different and bold enough to warrant being made while also being faithful to The Chronicles of Narnia books" No, plain and simple. Fans of this series just wants to see a faithful adaptation of a beloved work. Not "different and bold" aka updated for modern audiences.

I will give you points with Lion, Witch and the Wardrobe being the best of the three films made by Disney. The failing of the next two were one of the reasons as to why they stopped making them.

No one wants a "a very new take on Narnia. It's all about rock and roll," we want a faithful adaptation. Don't fix what is not broken. As someone said below the LotR was not 100% accurate to the books, but Jackson made sure to honor the work and is known today as one of the greatest book to film adaptations. At this point, Gretta is far from doing that.
