Not sure what prompted the retrospect, but found this in our local media.
Sci-Fi TV through the years
Some fine shows appear in this slide show but several excellent ones have gone missing! Firefly for one! Also Space: 1999, Outer Limits, Twilight Zone, original Battlestar Galactica, Star trek Next Gen, and The Avengers (If they include the Prisoner, I feel Emma Peel and John Steed deserve a place).
So what are your favorites that have been omitted from this? There are so many excellent (and not so excellent) sci fi show out there.
This also brings up a common debate amongst geeks. What constitutes sci fi? If they include Superman, why not X-men or Batman? Are they true sci fi or comic book heros? Does fantasy fall into this category? I would put the Prisoner and Avengers in more a fantsasty genre but the zone is definitely grey.
So what elements does a show have to have for you to consider it sci fi?
