The original Star Wars trilogy has a firm beginning, a dark middle, and a conclusive end that ties up the loose ends before the good guys party the night away on Endor.
Although reviled by some, the prequels gave the fans insight into the events which took place before this and added context to some of the main characters' arcs, fleshing the universe out and paving the way for the saga to move forward with yet more sequels many years later.
There have been seven Star Wars movies to date and one big screen spin-off, and while the storytelling has been tight thorough for the most part, unanswered questions linger in a galaxy far, far away.
The Force Awakens tabled mysteries to build suspense ahead of The Last Jedi, but unsolved issues which left the fans stumped have abounded since A New Hope.
Although the forthcoming Episode VIII is expected to answer some of the questions its predecessor left behind, some of the mysteries of old will likely endure and haunt the franchise like Anakin's Force Ghost at the end of Return of The Jedi's special edition.
