Unfortunately, this is so very, very true. See here for details. I was horror struck to discover that another sci fi and a long running much loved one (to me as well) was getting yanked.
It will join the (sadly filling) graveyard of really good scifi, fanstasy and supernatutal shows.
That's another thing, has anyone notived the trend, you never hear of(no offense) drama, and these other shows getting pulled off the air.

The Petition has already 20, 856 signatures. So if this to you guys is as bad as it is for the rest of us who are so tired of shows with poor characterization and storylines, sign!

I was expecting SG-1 to end soon. At least we'll still have Stargate Atlantis!

I signed the petition. Why do they always cancel sci-fi, fantasy and supernatural television shows!! Grrrr......

And what, Survivor is like on its 21st very very unpopular series, and they dont pull it!!!!!!

That's my biggest problem with tv. If a show doesn't perform well on one day because the football grand final or something is on the other channel, they push it back to midnight or just pull it and decide to put reruns of an american sitcom or a 'new' (I use that term very loosely because NO Reality Tv Shows on television are actually new, just ideas recycled over and over again) Reality TV show.

In other words NOTHING good on television is ever kept on, especially when they're sci fi, fantasy, supernatural, children shows or even new shows.

I hate reality TV shows! I get enough reality as it is! And I also hate how they cancel so many sci-fi shows. Star Trek and Doctor Who are the only ones I know of that have gone on for a long time.
