The Threshold series has just appeared up on Youtube. The sound is sped up, presumably to avoid copyright recognition. But the show is great. If you wonder why Peter Dinklage was cast in Game of Thrones this is a nice sneak peek (peak) (peke) on that performance.
It only lasted 1 season, and they shoehorned a finale into the last episode, but a lot of it was very good. Post X-files, pre-Fringe type stuff.
