My 3 and 4 arent even on the master list. YIKES.
1. Firefly: No power in the 'verse can top it.
2. Buffy & Angel: Joss Whedon is my master now.
3. Twin Peaks: The best thing on TV before Joss came along.
4. Gargoyles: The greatest show that people never believed was any good, and the best cartoon of all time.
5. Hercules & Xena: Made Saturday nights fun.
6. Justice League Unlimited: True to the source like Batman:TAS, but with the entire DCU
7. V : well, I LOVED the two mini-series, and remember the regular series as being OK, I really have to re-watch these.
8. G.I. Joe: um, action fantasy? Its some sort of fantasy.

9. Transformers: transform, and roll out.
10. Friday the 13th The Series: Another show that people will not believe is good.
