I just finished reading FF #22 and Fantastic Four #611, both of which were great reads, and was overwhelmed with the sadness that Hickman's run is coming to it's end. Three years ago, Hickman embarked on an extremely complicated story involving many characters. While at first even the most seasoned FF reader (myself included) got a little lost with the immensity of the tale, it eventually all rolled together into an amazing, well thought out story that involved and affected every main character in the series, as well as introducing interesting new characters as well.
We still have FF #23 to look forward to, but otherwise that's the end of the line.
I believe Hickman gave the team the shot it needed and showed why the Fantastic Four is such a great team and family. They have heart. "They are a perfect family in an imperfect world." I should hope the team picked up some new readers these last few years so they could see what the Fantastic Four is really about.
I'm at least happy to say that even with all the complexity, nearly everything has been wrapped up before the creative team change. I have no problem saying that after this, Hickman takes a top spot in my favorite writers list. So, thank you Mr. Hickman, it was a 'fantastic' run. World's Greatest Comic Magazine indeed.
