I feel exactly the same about Prim. I really wanted to like her as a character, but her death didn't affect me hardly at all, and I don't normally need much excuse to cry about characters I'm attached to
Ditto on Sookie Stackhouse as well. Really enjoyed the books at first but I haven't got the newest one yet, can't get excited about it. There's no shame in just ending something, but I guess while people still buy them, they want to keep churning them out.
