Anyone know when/why the show "Threshold" ended or if it will be back with new episodes?

Answer 1

Threshold was unfortunately cancelled because it never was able to capture the ratings the network had expected. The episodes that were never aired during the the regular run are available on the DVD set and will be aired on the Sci Fi channel at some point. At this point I would say any new episodes are unlikely unless it receives very good ratings while it is being aired on Sci Fi. Sorry, I enjoyed the show myself and it is shame that terrible sci fi like Heros continues when superior shows are cancelled.

Answer 2

they took the best parts of the show and put them into Heroes
