San Francisco has the firepower (or should that be the earthquake power) of a very strong lineup. It was the 30s version of the blockbuster and similar to modern blockbusters, the script is a little thin and sensationalist.
Likely something that your mom would like. two married people go through life having an affair once a year at the same hotel. They talk about their lives and how they have changed but they still have each other. Slightly barfy.
