The curious thing about True Blood is that, even if you’re not that interested in their relationship, there are other things to enjoy, notably the supporting performances and the mostly efficient plotting.
True Blood also sometimes seems to have a cast of thousands, despite being set in a small town, so all sorts of subplots have been simmering. The show evolves, as it has before, by starting the new season with a few more. It's a little wearing sometimes, to be honest, though it has enough narrative strength to keep hard-core fans happy.
