There are only a few characters in comic books that might deserve to be killed off multiple times, and this issue leaves the reader hanging as far as the final kill count for a very famous X-man. Extermination has been a really solid cross-over that’s not a cross-over. Appearances by members of the Blue, Gold and Red X-Men teams, as well as Old Man Logan, X-Force and plenty of others, not only keep the book interesting, but it reminds readers that just because a certain title is soggy doesn’t always apply to the characters themselves. The book, regardless of the conclusion, also promises to simplify things by sending the younger versions of the X-Men back to their home time zone.
