What do you think is legitimately canon? Obviously Whedon's involvement is canonical. And Betta George becomes canonical by association which makes me think Lynch's previous stories are canonical (and also awesome). This leads me to believe that the Spike series is canon as well.
I italicized the things I thought were NOT canonical.

The "After The Fall" arc is considered canon, and the last "Spike" miniseries must be, because that;s where he gets command of his space ship, but I don't think that anything else from IDW is considered canon.

But After the Fall references both Spike: Asylum/Shadow Puppets and Spike: After the Fall.

It's all canon. But I've heard such terrible reviews about Aftermath that I'll be leaving that out. Last Angel in Hell is supposed to be good, especially since Juliet Landau actually took part in writing the Drusilla arc.

And by that reasoning, Brian Lynch = Canon
All Others = Not Canon
