Yea, if you're watching a show on SyFy, where you know it's typical toget 10 episodes, then a half year long hiatus, the hiatus isn't so likely to hurt the show, as you know, being a SyFy viewer, that's the way do things (Especially if it's an established show).
But, a Network show, that is brand new, and only airs 7 episodes, before a long hiatus, it's really got a long uphill climb to survive into the next season
