I did read all the HP
books eventually.
The first one was a slog because Rowling's writing was so bad.
As is true with most activities, with time you either get better or worse.
She got better, but it was pretty much "two steps forward, one step back"; that is, her writing was still uneven.
So if it no longer was a solid slog, it was still "sloggy".
By the last book she had improved a bit more, but not enough for me to ever consider re-reading any of the HP books.
Still, some characters were memorable if only because of their eccentricities. I liked professor McGonagall.
I especially liked Luna Lovegood...can't recall hardly anything about her, but I can remember that at the time whilst reading her scenes, that I liked her, and thought her a rather astute person, and a deeper character than the other "yutes" (including HP) .
