Sanctuary is up in the air right now. The whole Cabal thing was settled in what, a single episode. I'm not sure about the cast shakeup. They didn't give Invisible Girl a fair shot and I'm not too fond of Freelander (could they have come up with a better name for a freelancer??)
Nice to see some of the Eureka cast when that show isn't on (just like the cameos in Warehouse 13).
Sanctuary seems to be grasping for a theme.
Rapidly changing arcs and characters are not a good sign and reminds me of the fall of Atlantis(the SG series, not the city). Even more troubling is the sudden influx of CGI monsters, like the are trying to be Primeval the BBC series.
