3 and 1/2 to 4 stars. Really good. Very reflective. Clearly, this was a labor of love, written with care - something appreciated by any booklover. Maybe a little over the top sometimes, but that's about all the negative there is, unless you don't agree with the author on certain points, but that's par-for-the- course, isn't it?
I only read about half as I haven't read some of the books, but I will probably continue when it become pertinent. (ie, when I've read the books and/or develop a sudden interest in the characters despite not having read the books)
