* ScrewedByTheNetwork: 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, InvisibleAdvertising was at full force, as there was very little faith in the success of the series.
* SimilarlyNamedWorks: The series has the same name as a ''Series/StarTrekVoyager'' episode written by this show's head writer, Brannon Braga.
* WhatCouldHaveBeen: 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 [[WritingByTheSeatOfYourPants written on a go and with no idea what next]], this makes ''Threshold'' stand out.
