Fifty bajillion wormholes in the episode, plus the return of Beverly Barlow, and they couldn't even be bothered to either address the fact that we've abandoned not only one, but two, timelines, and we've never found out much at all about The Consortium. And really, would it have killed them to have Nathan Stark make an appearance?!
I haven't been this annoyed since Stargate SG1 ended without ever finding anything out about the Furlings.
