I have two sides on this.
A part of me doesnt really give a s***t. Mostly because I had no plans on watching the HBO series anyway. I don't have much hope for remakes.
But the Harry Potter obsessed side of me does care a little, most because of my everlasting love for Alan Rickman, but also because it might seem like James Potter and the marauders (who I'm going to assume is most likely gonna be casted as white) are racist. It also doesnt help that scenes with the Maruaders most likely will be in the 70s. I might be blowing this way out of proportions tho.
