It’s all relative
Here’s a stunner for Joss Whedon fans: “Firefly has more viewers than Buffy or Angel, but it is also Whedon’s most vulnerable show. That’s because it airs on Fox, which has higher viewership expectations than UPN and the WB.” (from a Houston Chronicle article) Firefly has more viewers than Buffy and yet it may not survive? Grrr arrgh!
