I will say that Kindred is a big swing for Spencer. He's a very gothic and dark character, sure it talks in slang and all, but it's definitely a character who is very dark, whereas most of Spencer's writing on Spider-Man before and during his run is in a very comedic vein. I mean I can't think of another time when the Spider-Man comics was so funny. A lot of writers balance the serious and comedic stuff (none as well as JMS in my view, on re-reading his run, I was pleased at how hilarious it was) but usually they work in the Roger Stern 'middle mode', which is straight-faced but with some jokes thrown in or going dark.
Whereas with Spencer it's like there's an undercurrent of comedy throughout but behind or beneath it there is this really dark level of secrecy and horror, which is quite interesting.
I think ASM#29 captures the essence of that, because that comic is entirely serious without any jokes. There's a real sense of despair and longing there that Spencer really captured.
