I pretty much am cosigning with what people have said.
Models Inc. (I too still would like to know who got shot. I bet it was the kid)
Popular (I just started getting into that show when they cancelled it)
My So Called Life (Aren't we all still mad at ABC for cancelling this, bet their kicking themselves in the A$$)
Ned & Stacy (That was really a cute show, funny too)
As for Firefly, I never watched it. I should buy the DVD's cause I seriously ADORE Joss Whedon. The man is a SAINT for giving me Buffy for 7 seasons and Angel for 5 (although it should have been more, but that is a whole other thread
)
