John Byrne had drawn a bunch of issues before this, so I bet you thought we were moving into his run now, but we’re not. In the interim, the team on the upcoming Moon Knight book takes a brief turn and, as brilliant as Moench and Sienkiewicz can be, their work isn’t as suited for a family comic.
Having said that, there’s a great (albeit somewhat abstract) giant seamonster fight and Reed Richards turns himself into a rescue slide.
So, yeah, it’s still pretty good. It’s just very, very different from what you’d expect on this book in particular, and the change in mood and style wasn’t predicated on anything changing with the actual characters—it just picks right up in continuity.
