Since the wonder of DVD's I have re-watch this series again. Personally this is my favorite Star Trek series. I am a Star Trek nerd and will randomly watch different parts of Star Trek for background when I am working on other projects.

Deep Space Nine is the one series that I normally re-watch from beginning to end once ever year. It is easy to just power through them, which is pretty easy to do. One of the strengths of this series is that it has a series long story to tell while most of the episodes stand alone. The full story of Sisko starts in the very first episode and continues along in every season to develop the story and come to a sad, but fulfilling ending.

If you are on the edge of Star Trek, this is a great series to watch. I would not use this series to introduce a new user to Star Trek. It does avoid and make some assumptions about the viewers understanding of Star Trek lore.
