I can't say i ever knew or cared much for the Eternals and their motivations/actions before their movie and i highly doubt i'm going to be convinced to do so by this crossover. So this is going to be a lot of passes for me in that month and waiting it out again.

Doesn't help that it seems unlikely anything major will truely change about the X-men line from it's outcome, seeing how it occurs in the middle of ongoing stories entirely unconnected to it. So it seems the crossover will come, interrupt several titles for a month, go and leave nothing of value behind beyond having another group established who for some contrived reason has it out for the mutants.
