Yeah, a Superman ended each Crisis but the first one wouldn't have been able to do it without Barry Allen, all the mages on multiple Earths, Spectre, Supergirl, Alex Luthor, Darkseid, etc.
The set up for IC #7 was great with all the vilains aligned in Metropolis, the reappearance of Doomsday and Superboy Prime riding high after killing Conner. Come to find out all the villains shat themselves at the sight of the big time JLA members, Doomsday got 3 shotted and then Superman beats SBP while standing in K-nite that only affects him.
