Oh, absolutely. But then, I have no doubt it will be. They'll probably be going to the original pitch for the series at least as much as the set of novellas it became.
I think the Safe Negro Travel Guide was more central to that pitch, as it allows its characters to travel the country and encounter the supernatural, and I'd expect a TV series to make good use of that. After the first novella, I think a series would do well to take a different route than the novel does, and maybe pick up on some of those stories later on.
