I liked this issue. The stuff with Ben and Reed as kids were great, and having the possibility that Johnny is still alive gave me hope that there is one less pointless death. I also like that the depiction of Molekevic has always been consistent and he's not a totally evil cookie-cutter mad scientist villain.
Also, the "Fantastic Voyage" made me feel nostalgic when UFF was exciting, which was during Millar's run. And ridiculous sci-fi which is in comparison to "President Thor", zombie universes and Atlantiss actually made me feel good that we would have a decent swan song for UFF.
I disagree with some of the earlier statements. The most boring arcs were mostly from Carey's run because he got so swept up with all the sci-fi geekdom stuff that he failed to make very compelling stories. Four Cubed was a letdown and I didn't care about God War. I don't think anyone cared about all the new characters Carey introduced. The Silver Surfer and Ghosts arc, which actually went closer with the crazy "silver age" stuff was actually better, and of course everything from Millar's. I think the only one who was able to write plausible and realistic sci-fi and make it exciting in the UU was Warren Ellis.
