CN Winters, Susan Carr, et al. do a fantastic job of producing a 'series-like' after-Buffy spin-off. Seriously... it has the stories, the character development and subplots, the artwork and even sound snippets. It's a great read that plays like a spin-off and not just BTVS: Season 8 (which Joss is doing anyway in the comic books... check them out).
The thing you'll notice at the start of Season 1 of Watchers is that Buffy, Dawn and Xander are nowhere to be found, but the rest of the BTVS: Season 7 cast are there.
Faith, Willow, Giles, Robin, Kennedy (who has become a favorite character of mine in this series... they have done a fantastic job with her!), Vi, Andrew and Rona are all present (though sadly, some of our characters end up dead in the course of the series).
WaTchers is currently in their last season (season 5) and I urge everyone to give them a real chance and head over to www.thewatcherscouncil.net
