As a die hard Buffy fan myself I learned never to expect a sci-fi show to ever get nominations.
I know how you feel.
I've been hearing all over the place about The Shield being ignored. I've never watched but I know when it first debuted it was big with the Emmys. It's a shame this year because it was it's final season.
My only issues are that Justin Kirk from Weeds and Cobie Smulders from How I Met Your Mother weren't nominated.
With television its so hard because there is SO much on tv that there will always always be snubs no matter what.
