Multiple relationships, many-to-many belongsToMany, right?

Question

Laravel

Hello, I am a complete beginner in php and even more so in Laravel.
Is it correct to use multiple relationships in a project, many-to-many belongsToMany?
Those. like a movie site. There is a post about a film, one film can have many genres->one genre can have many films, one film can have many countries involved in filming->one country can shoot many films, there can be about 10 such connections in this particular case. Is such an implementation via belongsToMany correct? As far as I can judge with my little knowledge, when displaying a post about a movie, there will be a lot of requests to the database. Or am I not understanding something?
