Hickman's run has been marked by some of the best Fantastic Four writing I've read but this one-shot is not up to snuff. The shocker that they were inside a human body was totally obvious and the way the team spoke about the structures as if they were interstellar just came off as cheesy. It was a twist to see that it was Willie Lumpkin as the patient but even that was muted. On a side note, I guess the FF have discovered how to end malignant tumors. Which I guess means no more cancer storylines in the 616-marvel Universe. This kind of scientific advancement should make oncology and medical school very interested for aspiring doctors.
