Modes of address:
Leaves the ending unresolved, giving no closure and a lot of questions still needing to be answered. This leaves the viewer walking away potentially with a unsatisfied feeling as they don’t know what just happened, though this is usually intended by the director.
Leaves the ending with full closure. This ends the film, ties up all loose ends and has no continuation past the film.
Has different stories intertwining with each other, soaps are more likely to use this type of narrative.
Doesn’t follow from start to end, unclear order of events and jumping through time.
You go on an investigation throughout the narrative and discover the story as they do in the film.
