Here’s a new one:
Character is in a situation that triggers a memory. Now we go with that character into the memory for a while, a minute, two 30 seconds, whatever, but it’s long enough to shift context and follow a sub-narrative. Then we return to the original context, the present, with character’s face absorbed in the memory. Another character then has to jog the first character’s attention. “Joe? Joe” Where were you?” And the first character then has to come back, pretend it’s nothing and resume the first nbarrative thread.
That whole jogging of the first character’s attention is completely unnecessary. It’s stupid to pretend that just because we in the audience experienced a time shift with the second thread that the characters in the first context also experienced it. The whole thing could have taken place in a split second for them. I don’t mind the actual context shift itself, I just hate the way they transition back. It’s so rote, total cliche, and they do it in the finest of dramas and films. Just skip it completely.
