Oh I like Prophecy Girl well enough, just prefer other episodes to it.
Although it is better than Harvest. But you sort of need it to understand the series.

It's hard to do lists with serials. They didn't do a bad job considering this was meant to be a teaser marathon. I'm guessing they just got sub rights to Buffy. And are advertising with the marathon. Now all they need is Angel and Dollhouse, and they can do a Whedon weekend.
