I like it.
I still feel like it's a massive mistake though. It doesn't matter how good it is, it will always be viewed negatively next to the original based off nothing but nostalgia.
It would have been much smarter to base the show around the cursed child story and focus on the relationship between James Potter and Scorpius Malfoy. You would have the origional material to base the plot around but there is no where near the same amount of it so you would also have artistic freedom to pad it out how you want. You would also have a far greater margin for error as people aren't so attached to it and would be more forgiving.
