Reading that, it occurs to me that I've already forgotten who those non-canon characters you referenced are. So few of the characters managed to really make much of an impression.
Though we'd probably disagree on some of the details, I would also rate it in the 6ish/C-ish range.
I never expected it to be much more than an elaborate fanfic. The mold was set by PJ twenty years before to be just that. Considering the allowable usage of canon, the estate involvement, and such, I was surprised it turned out
that good.
