Battlestar Galactica: The Resistance is an online series that aims to fill in the gaps between seasons two and three of the Re-imagined Series. The webisode series was written by Battlestar Galactica veterans Bradley Thompson and David Weddle, and directed by Wayne Rose. The entire series is 25 minutes long in total, divided into 10 episodes. In particular the webisodes chronicle Duck's and Jammer's motivations to become suicide bomber and collaborator respectively.
I'm going to stick to must watch shows only rather than list my entire Sci-fi library. If there is something not on this list it may be because I haven't seen it either, like any of the Star Trek series. I've seen bits but not enough to give my vote against or for it.
Also I have a few shows multiple times to show webisodes and things that run concurrently with the show
