DC Reboot
I honestly quite like the New 52. But was it really a reboot? Two titles' continuity were kept, which basically fucked up the whole thing, and there is WAY too much history in those comics for an average reader to make sense of them. I want to completely erase all previous continuity and start completely fresh with every single title. Also, no alternate Earths (Except in Elseworlds and Watchmen), retconning, and each character can only be killed (and revived) three times. If a writer wants to kill them again, they're gone forever.
This new universe was caused by Doctor Manhattan fucking with the timeline, similarly to Rebirth.
