Good. The show's been on a downhill slide for a while. Better to go out leaving (some) people wanting more. Plus, the actors playing vamps aren't getting any younger. At a certain point, it starts to look ridiculous. Stephen Moyer and Kristin Bauer van Straten in particular have aged noticeably since the start of the series.
Kristin still looks fabulous, but she's in her mid-40's and that wardrobe requires her to stay really thin. If she had a little more weight on her bones, she'd look younger.
