I'm curious how the next season will go, because from memory, they still have the back half of the first book to go, and fuck-all happens in it. Will they commit to a prequel season or try to string some plot together while telling the prequel story through flashbacks?
Dunno why people say it sucks, it's (no real spoilers) a genre staple ending pretty much. Leaves stuff open for a sequel, as they do, but still finishes off the main plot.
It'll get real interesting in the next two seasons (I've read the books). The world is really cool but story-wise the books do stuff you can't do on TV, so we'll see how they can wrangle it.
