So of the four sci-fi/horror genre shows debuting this year (Supernatural, Threshold, Surface, Invasion) I've caught two and a little bit of the CBS one. All I can say is that Threshold didn't manage to keep my attention for more than a couple minutes, so I can't really judge it. Supernatural seemed ok, right up to the ending, when it was just daaaaaamn. As for the NBC offering, so far the acting seems pretty weak. I'm not sure what to think of the alien/monster/fish things. They seem pretty inconsistant in motivation and abilities...
