Being able to free roam and complete unfinished missions invalidates the ending to me. When the map is panned out it states the father has been defeated and all of Hope county is liberated. The story in Far Cry 5 is a mess. It pulls in too many directions. There were 12 writers on staff and I don't think the writing teams communicated with each other.
