Aaron's GR is great.
This issue starts a new storyarc for GR (and crew), although its not a great "jumping on point" for new readers. This issue focuses a lot on Caretaker - a character that Aaron has really developed well. The cover does not even have Danny or Blaze on it. The Ghost Riders from the future are hysterical (and provide a little context) and allow for a lot of future storyline possibilities.
Aaron's handling of GR has been unique, grisly, and entertaining. I have heard it described as "redneck," but that term doesn't adequately depict Aaron's flavor of the series. But like Aaron says in one of the letter columns: he gets to write stories with nunchaku weilding nuns in them. That's good stuff.
