"Hooked on Star Trek" worked for me.
For the last couple months, we've been watching the Star Trek Voyager series. We started by signing up for a free trial period of Blockbuster On-Line. We got to rent 3 DVDs at a time. So far, we've rented season 1 and season 2. We've just started into season 3. Last night, we watched DVD #2 of season #3. There seems to be 6-7 DVDs for each season. There's 4 episodes per DVD. (We've also been copying each DVD using DVD Shrink. Shhhh. Don't tell anyone! Nobody reads our blogs anyway!)
The 'gist' of Star Trek Voyager is the crew gets pushed 75 years away from earth. They end up travelling through a quadrant of space that has yet to be explored by humans. Along the way, they pick up a few passengers and make a number of enemies. Our favorite episodes usually involve the Borg (enemy robot-like race), alternate dimensions, and time-travel. We got hooked on Star Trek way back in the day (high school / college).
We're such nerds.
