Something that I've noticed, both in TV and movies is that often, when someone dies, the grief of their passing is very brief.
For example, "Death on the Nile".
At the end of the movie, when everything is solved, the girl is going off with the young Communist and she's happy......and rather oblivious to the fact that her mother was violently murdered only a day or two before. To say nothing about the positive notes the survivors are leaving on....considering that the crew are about to unload five dead bodies after they depart.
Or, "The Streets of San Francisco" in "Beyond Vengeance" where
Stone's daughter's roommate is murdered just after the daughter left her, but a few days later when the crime is solved, she's a bouncing ball of joy.
It's especially bad because it can get rather confusing to trying to figure out who is the crook in a mystery. Ie, so&so was rather quipped with our hero after one of his men gets blown up in our hero's car. Gallows' humor or was he expecting the blast or is it just lack of grief that is so often seen in productions?
