Q: Why is DC One Million the best crossover ever? -- @SerialWordsmith
A: Whenever I'm asked about my favorite DC crossover, the one that I always go with is Invasion!, and I think there's a pretty good argument you can make. It's done in three oversized issues, so it's quick but still feels like an epic story since they're all 80-page giants, it has a great use of some often-neglected parts of DC's cosmic side, and there are pretty fantastic tie-ins from creators doing career-best work on books like Suicide Squad and Animal Man, and it really did add something interesting to the DC Universe.
Then someone mentions DC One Million and I realize that yeah, I'm wr-- I'm mista-- I'm misremembering things, because it's definitely the best. I mean, it's not just the best DC crossover, but it's probably the single best crossover in all of superhero comics.
