In the aftermath of 2015’s Secret Wars, Marvel launched the X-Men in a controversial new direction. We learned that the Terrigen Mists circulating the globe had become poisonous to mutants; as a result, both the X-Men and the Inhumans were faced with a terrible problem. If the Terrigen Mists continued to spread, then the mutant race would become extinct; if the Terrigen was destroyed, then the Inhuman race would become extinct.
That arc’s now building to a head in the current Inhumans vs. X-Men event, which revealed that the Terrigen Mists would soon contaminate the entire planet. Within a matter of weeks, Earth would literally become uninhabitable to mutants, and no more mutants would be born. This led to the X-Men launching a desperate attempt to destroy the Terrigen, but the younger Inhumans stalled their plans.
But the arc hasn’t landed at all well, and there are real problems – issues that are still undermining the story. Where did Marvel go wrong?
