I am extremely disappointed that there is a House of M crossover. It would seem that Victorious as Magneto's son would be the tie-in. That said, I hate crossovers.
I buy Runaways (or whatever) and I enjoy Runaways. I don't want, half way through the series, an issue to show up that discusses a story that occurred in another book. It would be like watching an episode of Sopranos that, for some reason, commented on what happened in Sex and the City (both HBO, both NY). It's out of place, and irrelevant. The only reason for it is marketing, and I have not time for that.
I thought with the advent of the Ultimate universe's policies of putting crossovers into stand alone minis would do away with this obvious gimmick, but as Disassembled and Identity Crisis proved, crossovers are staying. Blech.
In any case, really enjoying Runaways. Damn good book.
