How to search a list of movie of a one genre or various genres?
Hello,
I am having a problem with a route that before worked but now after 6 months it doesn't work well.

https://api.themoviedb.org/3/movie/popular?api_key=MI_API_KEY&language=es-ES&with_genres=80

Before that route returns the movie popular list that contains the genre 80.
Right now it doesn't matter what genre number I put on it because it returns the list of popular movies regardless of the genre.

I believe that using Popular API Request it was never possible to filter using genre.
Not that I know.
I don't see this feature on the page in DOCs.

Has there been any change or is there no solution?

What you can do is use Discover, filtering for one or more genres and specifying "&sort_by=popularity.desc".

At the moment when I was an app it had been worked but few days ago when I opened it that it was not work but the idea that you wrote in the last line it's a good idea for change in my code. Thank you so much!!!

What's not working? This query:

https://api.themoviedb.org/3/discover/movie?api_key=###&with_genres=80

Is working properly, so what query are you using?

I used this query:

https://api.themoviedb.org/3/movie/popular?api_key=MI_API_KEY&language=es-ES&with_genres=80

But the idea that you and @ticao2 have written it's works well in my code. Thank you!
