Except for one.
All Things Philosophical's Season Six.
This is one of the few virtual series that actually feels as if it could have been written by ME.
It doesn't try and overdo it with the guest appearances, there's a few highly interesting oc's in it. And all the chars feel right.
It might not be as Spike heavy as I'd want it*g*, but other than that, it's the best Virtual Series I've found so far.
Definitely something to be reccommended
