I watched Licorice Pizza yesterday, it was good. I'll be watching it again Friday Dec 24. I loved the 70s soundtrack and the immersive experience of the movie. PTA says there was a lot of running in the movie because as young adults, the main characters didn't know where they were going. That's one of the reasons Cooper Hoffman had many jobs in the movie.
As for the plot summary: The romance starts off at a school photo shoot which is point A. It then twists and turns and finally they end up running into each others arms which is point B. The movie develops around their relationship.
