Today I didn't get around to doing more reading into different branches of Christianity, but I did finish reading Harry Potter. (I've been writing reviews on goodreads.)
I can't experience these books with a completely "open mind" because I've been trained to think about different genres and other meta literature this and that—search "philosophy of literature" if you're interested in this topic more...
In short, I would say that the Harry Potter series is very entertaining. There are likeable characters and the books are very readable. You could call them "page turners".
Whether or not they reveal valuable information about the nature of the universe or human interactions, that is a different question. For the millennial generation, they are definitely culturally significant, but I am not sure if they will be for subsequent generations.
I don't feel a particular desire to (re-)watch the movies after reading the books, though I would if there were some social reasons for doing so.
I hope everyone has been having a good Sunday. For me, it has been pretty relaxing—talking with some folks on the Internet and catching up with studying various things.
