The plot of the movie is that the mutants no longer exist and the y are now being scientifically made and not born. logans DNA formula is with the doctor hence he has an indirect daughter. All these kids have escaped from the lab and are heading towards Canada for safety. the child of logan somehow manages to meet logan and charles xavier who both die in the end. It is still unclear of why logan dies and why his regenaration capability is not working. the performance by the actors is just above average. everyone couldve done a better job. And logan shouldnt have died the way he did.
