Oh, cliffhangers are great, I just didn't feel like much of anything was resolved. They left a lot of questions and gave basically zero answers.
I liked the HP Lovecraft tie-in, too. Forgot to mention that. I wasn't sure I liked them turning the dragon sword lady from Bobby's past into a...whatever she was, though. That was a Chekov's Gun that didn't quite work for me.
All in all, it just felt like it was lacking the 'oh shit' moments of past finales.
