"Mars LIVES!" from Brightest Day #12 (DC, 2010) by Geoff Johns, Peter J. Tomasi, Patrick Gleason and Irwin
A dream sequence that sees Mars reborn is very representative of Brightest Day series/event. After all, whatever Brightest Day established, it was as fleeting at J'Onn J'Onzz's vision with the coming of the Flushpoint. What a waste of time this was. They took a whole year (the same with the JLI series on the off-weeks) setting up a new status quo for a number of resurrected stars, even left some threads dangling for upcoming projects. And then, pfft. A whole year setting up a new Aqualad - pffft. A whole year re-shuffling the identity of Firestorm and turning him into a time-bomb - pffft. Even the return of the Swamp Thing was immediately subverted by a mini-series in the Old52. Brightest Day really puts the lie to the idea that the New52 was well-planned ahead of time. Or if you're cynical about it, it was planned, but they still wanted your cash so made us believe this stuff was "important".
