I believe the phrase is "jumped the shark"

We just watched the end of season two of True Blood. Season one was quite good, though rather dissimilar from the books (Dani says; they're in my reading queue). Season two continued that dissimilarity but got just plain weird. Spoiler warning, in case it matters: Really, a supernatural being who locks the entire town under mind control toward the goal of summoning Dionysius so she can marry him? And the way to any god's heart is through, well, sacrificial hearts? Ew. I believe we shall both give season three a pass.

I think I'll go scrub that out of my brain with some Stargate: SG-1.

(And a minor Netflix kvetch: I do not want to separately manage DVD and instant-view queues; I want the latter to be auto-generated from the relevant subset of the former. Unlike with DVDs it isn't really a queue; I can watch anything at any time, so it's just a matter of navigation. It wouldn't matter if things available via streaming stayed available, but they seem randomly become unavailable, at which point I have to move them over to the DVD queue. That could be easier.)
