Answer 1

On solution is to override genre field in your serializer, to accept a list of strings like this:

class MovieSerializer(serializers.ModelSerializer):

    genre = serializer.ListField(child=serializers.CharField())

    class Meta:
        model = Movie
        fields = [
            'popularity',
            'director',
            'genre',
            'imdb_score',
            'name',
        ]  
    def validate(self, data):
        genre = data.get('genre', [])
        genre_obj_list = [Genre.objects.get(name=name) for name in genre.all()]
        data.update({'genre': genre_obj_list})
        return data

And on validate method try to fetch each object by their names and put in a new list and update data result with new list of objects. (I know it's not the cleanest solutions, but it works fine)

you could also try to use MethodSerializer or define a GenreSerializer and fetch objects in that by their names and use that in the parent serializer as an input.
