That's weird, I was sure we discussed Granny already! Oh well ...
I like Granny's practicality and the fact that she subverts the old tropes about magic (e.g. using magic to help people or yourself). Granted, these tropes are subverted throughout the books and by most magic-users (wizards included), but Granny does it in a no-nonsense way that seems to say, you can either understand or you can fall behind, it's your choice. No wonder she tells Perdita (in Maskerade) that she, Granny, ain't no good at teachin': she probably could be very good, but she doesn't have the patience to teach, possibly because the modern teaching methods say that you have to wait for all the students to understand before moving on. Trouble is the kids know that, too, and some of them take advantage by acting out and making trouble for the teacher. Granny has no truck with any of that: if you don't want to learn, she doesn't want to teach. (Granted, she doesn't want to teach anyway.)
I also like Granny's pragmatism, frugality, and the sense of making do with what you have. Not for her are the fancy tools of the trade (or "toys", as she would describe them, probably with a disdainful sniff). She sees no reason to move with the times or adapt (although, granted, she's an elderly lady, so I reckon she's earned the right).
Finally, I like the fact that she thinks about what she's going to do or say before she does or says it. I wish more people would do that - it'd save a lot of trouble.
As for Granny's less admirable qualities: she's very secretive about her plans. She tells people it's for their own good that she doesn't tell them her plans, but I reckon she just wants all the big scenes for herself. When she defeats an enemy, she becomes very smug - some would say, insufferably so - although no one would say it to her face (at least, not more than once). We see this in LL and CJ, but not in WA (which is understandable - she is distracted by family matters) or in WS (which, again, is understandable - it's an early book, and the ending should really be Magrat's).
Granny doesn't really have many (or even any?) enemies to face after CJ, which is odd. She hardly appears in ToT (the only witch there is Nanny IIRC), and when she appears in the Tiffany books, she's more in an advisory role. Again, this is understandable - it's Tiffany's time to shine - but part of me wishes we could see Granny take a more active role, like the old days.
Anyway, that's what I think of Granny.
