The Back to the Future movies seemingly established a time-travel rule, but their Christopher Lloyd-starring sequel seems to defy that logic in one significant way. More often than not, it is assumed that the Back to the Future franchise consists of only three movies that perfectly tell a well-rounded story before neatly wrapping the overarching storyline. Like most time-travel flicks, the Back to the Future movies are not bereft of timeline issues and narrative inconsistencies. However, they perfectly manage to tell a well-rounded story, which concludes on a satisfying note with the third film.
