So much love! OK, first of all, it’s in script format. No doubt that disappointed some--it's not a new novel. But for me it was a plus. For one, none of the stylistic tics that have bugged me in Rowling were present: No jarring book-saids or adjective abuse. It’s not bloated in plot; there aren’t any plot holes that I can see. One of my friends said she did roll her eyes at one aspect, but even with her that was a minor complaint.
There's another way I find this a past due recognition. The way Gryffindor dominated the other books and all the Slytherins were depicted negatively really bugged me. One quarter of the kids are cool and another quarter evil little tyrants or their followers in the making? Ravenclaw and Hufflepuff still don't get their due but at least there are heroic Slytherins in this one and some Gryffindors who... well, let's say make some mistakes. There's one line of McGongall's I've been waiting for *someone* to say to Harry Potter for years: "The lesson even your father sometimes failed to heed is that bravery doesn’t forgive stupidity."
A lot of the lines are witty, out and out funny and/or wise. There are some old favorite characters that unexpectedly show up--a highlight of the book for me. And I love, love Scorpius beyond measure. In fact, in the immediate aftermath of reading this I'd name this my favorite Harry Potter story. No doubt partly because it's been a long time--I hadn't realized how much I'd missed them all.
