Screwed by the Network: The network screwed the show over by switching it to a bad time slot and then cancelling it one day later. And prior to that, Invisible Advertising was at full force, as there was very little faith in the success of the series.
What Could Have Been: After cancellation, details on a number of future plotlines emerged. What made them further interesting was the fact the series had a clear, planned-ahead goals with it's story, being written from the start for a three-season series. Considering it was produced in the era of "mystery box" series, all written on a go and with no idea what next, this makes Threshold stand out.
