TV series / movie serial
Film covering more than one showing.
It may be a movie:
a) with the same theme and characters, when every next episode is a continuation of the previous (eg TV soap opera);
b) all episodes are connected by the place of action (eg, city) and by the main characters, but each episode presents a different situation;
c) cinema movies or TV films (or TV versions of staple cinema films) form an integrated whole.
