S2 did mutate (hee, pun, I slay me!) into a Buffyish-style horror, and I prefer the first, snarkier, darker season. But considering 9/11, I can see why the studio had them rework the formula.

As to Max/Logan? Sigh. One of my all time fave OTPs. The virus thing did get solved in the authorized book sequel (yes, I am pathetic enough to have bought those). I guess they didn't know they'd get cancelled. Ironically, Fox cancelled it because of Firefly (another great show) which they cancelled double quick too. Sigh.
