2. any Star Trek. I loved Enterprise. really I did. If they had the cancel it, I only wish they could have had another Star Trek series to take its place.
3. Dark Angel
I loved the X-files until Mulder went away. After that it was just painful. I really wanted the show to end by that time. I just couldn't care about supersoldier-baby William, either. And I hated, HATED how they killed off the Lone Gunman guys. But I miss there not being something like the X-Files around (it was a staple in my life since half-way through the first season, and my massive Aspie crush on Mulder got me through some very rough times. LOL). Now all I have to give my life meaning is Sci Fi Friday Night with SG-1, Altantis and Galactica (and my massive Aspie crushes on Daniel Jackson, Dr. McKay, and John Shepherd :p ).
