I am of two minds about this.
On the one hand, I think having a remake of an already perfect film, especially if it’s around 90% or so the same shots and dialogue, is completely unnecessary. From what I’ve heard, the books are different enough from the films so why wouldn’t you just adapt those instead?
On the other hand, out of all of the live action remakes of films that we’ve gotten thus far that are basically the same as their animated counterpart, this actually looks pretty good and the best that I’ve seen thus far. The lighting and shot composition of the cinematography is surprisingly great, and, despite some dialogue and character, moments being lifted directly from the animated film, the acting seems surprisingly naturalistic and doesn’t feel like actors just robotically going through the motions to look and sound exactly like the animated versions. I guess it helps having one of the main creatives on the anime trilogy being in charge of this. Despite being a near one to one remake, it does feel like this is being made by people who really understand what made the original work and know how to adapt it in a different medium. Even though the initial decision to make this film was done through corporate interest to make money, it does feel like the film creatives behind it really do seem to care a lot and are putting a lot effort into making it the best live action version it can be. Cash grab though it may be, it doesn’t feel souless.
TL;DR – unnecessary remake, but admittedly looks great and doesn’t feel souless because of the creatives behind-the-scenes seemingly caring and putting their all into it, despite being an obvious cash grab.
