Is this a good database design in 3NF?

I’m trying to understand how databases work by creating a movie theater database in MySQL. I created the following requirements and attempted to sketch out my ER diagram based on 3NF. A lot of resources said I should use associative tables, so I attempted to, but I am not sure if I am understanding the relationships between them correctly. Is this a good database design for the requirements? Are the associations correct?
