Deadpool, X-Men and Logan are 3 separate timelines

Alternative outcome stories in a fictional canon can be enjoyable.
Nothing new here....been around since 1961 in comics (Flash # 123).

Nice avenue in movies to bring original , popular Canon actors back for a bit.
Good way of explaining plot-hole mistakes and misdemeanors and re-adressing stuff and offering re-visits for the fan or fan-boy....or even fanatic.

Yep I sometimes and often dig on Multiverse in fictional culture and art. 

Problem?
