I didn't, but I assumed others here have. I read a review of the entire series -- it sounds pretty terrible.
In addition to lifting a book with infinite pages with Captain Marvel's help (Ultraman, who is said to be the exact opposite of Superman, later did it on his own) -- scans of which I saw -- Superman and the Green Lanterns apparently pulled the Earth out of a black hole. Unfortunately, I saw no scans of that.
I did however see scans of Superman singing Darkseid's soul to death, killing Mandrake while wearing in his cosmic armor, lifting the infinite book, as noted above, enduring the contents of the infinite book, whereas Earth 5 Captain Marvel was taken down by it, struggle with the speeding, 700 mile ship, etc. Neat feats, but terrible story, as far as I can tell. Just truly awful.
