It is interesting to look the concept of seriality, which we frequently discussed in class, through the figure of uroboros: the cycle of death and rebirth, so to say an infinite interruption.
The seriaity, as we defined it, also bears this relation of eternity and finitude: namely, that seriality presupposes the possibility of the final, and yet it could go on and on.
Many TV shows correspond to such serial structure (which is quite expected, they are literally serials), but the one popped in my head was a cult British sci-fi series Doctor Who. This show is a perfect embodimet of the serial infinite interruption, recalling uroboros image.
What makes this show distinctive is regeneration. The main character (alien called the Doctor, to put it it simply) is able to completely transform their body, while (partially) preserving their essence.
This plot device basically allows eternal broadcasting of the show, which goes beyond mortality of the human beings, since change of actors is narratively justified. Every renewal interrupts the flow, and these interruption anticipate re-birth, rather than definitive end.
Peculiar, that in recently aired 60th DW anniversary special episodes beloved characters from previous seasons returned: the Tenth (now Fourteenth) Doctor (played by David Tennant) and his companion Donna Noble.
Such return is not new for the show, it happened both with Doctors and other characters. The novelty is that Tennant's Doctor now can co-exist with all the following doctors, creating the possibility for him to return at any moment.
This co-existence creates a constant anticipation of rupture and repetition.
