A thousand thousands
The DC One Million event was kind of a weird one, it was quite an interesting concept (by fast forwarding the issues but one million months), but other than the presence of Hourman it has mostly been ignored in terms of continuity. This is a sense might make it easier to swallow this average tale involving Diana and the Amazons, but it was after all still average. Diana fights Amazons, Amazons fight each other, Diana is feared dead, people who have died since show up out of continuity (Magala) and so on. If there is any real plus it is the Deodato cover, but then again its the cover which means you don't have to venture inside. Some others got a good treatment on the One Million story arc, but this one is worth skipping.
