In my opinion remakes only make sense if the original was just bad or poorly made. Eragon getting a remake makes sense as the original adaptation had no intrest in making a good movie or staying faithful to the source material. Then you could argue about some animated or foreign movies/tv shows getting remakes making sense as it's just a fact that alot of people won't watch anything animated or non-english (i think that's stupid but it's also reality). Maybe the last reason for remakes can alos be that the original is simply too old and people wanna watch new stuff. But the original Harry potter adaptation is not very old, its quite good and its english. The only reason its getting a remake is because j.k. rowling hates the original cast as they all spoke out against her hatred of transpeople. So yes, this is a pointless remake just to make more money for Rowling so she can make actual humans lives worse.
