I want to make my own Netflix in C#, without using sql, only using dynamic memory (omitting video-streaming support). I thought about this class diagram. What do you think?

In my main program I have a list with all the existing movies.

Each user has 3 lists, the movies he saw, the ones I keep and the ones recommended.

I thought about changing this last one, by list of pointers, since it consumes less memory. Worth it?

The recommended ones are obtained through an algorithm based on the movies you saw.

This is my code:

Movie class:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace Libreria

 public class Movie
 
 public string Name, Description;
 private int Year_Published, Restriction_Age, Duration;
 public float Calification;
 public List<String> Category = new List<String>;
 public List<String> Starring = new List<String>;
 public Movie(string nombre, string descripcion, int calificacion, int año_Lanzamiento, int restriccion_Age, int duracion, List<String> categoria, List<String> elenco)
 
 Name = nombre;
 Description = descripcion;
 Calification = calificacion; //Calificar solo las vistas 
 Year_Published = año_Lanzamiento;
 Restriction_Age = restriccion_Age;
 Duration = duracion;
 Category = categoria;
 Starring = elenco;
 
 public int Sum_Of_Calification = 0;
 public int Times_Calified = 1;

 public void Rate_Movie(int calificacion)
 
 Times_Calified++;
 Sum_Of_Calification = Sum_Of_Calification + calificacion;
 Calification = Sum_Of_Calification / Times_Calified;
 

 public void Show_Information() 
 Console.WriteLine(Name);
 Console.WriteLine(Description);
 Console.WriteLine(Calification);
 Console.WriteLine(Year_Published);
 Console.WriteLine(Restriction_Age);
 Console.WriteLine(Duration);
 
 

User class:

using System.Collections.Generic;
namespace Libreria

 class User
 
 //Datos del usuario
 public string Name, Surname, Mail;
 public int Age;

 public User(string nombre, string apellido, string email, int edad) 
 Name = nombre;
 Surname = apellido;
 Mail = email;
 Age = edad;
 

 //Declaracion de las listas que contendran las Movies vistas, las no vistas, y las recomendadas
 List<Movie> Movies_Save = new List<Movie>();
 List<Movie> Movies_View = new List<Movie>();
 List<Movie> Movies_Recommend = new List<Movie>();

 //Precondicion: La pelicula a marcar como vista se encuentra en recomendadas
 public void Marcar_Como_Vista(int Number_Of_Movie)
 
 //Inserta pelicula en Vistas
 Movies_View.Add(Movies_Recommend[Number_Of_Movie]);
 //Remueve pelicula de Recomendadas
 Movies_Recommend.Remove(Movies_Recommend[Number_Of_Movie]);
 

 //Precondicion: La pelicula a guardar se encuentra en recomendadas
 public void Guardar_Movie(int Number_Of_Movie)
 
 //Inserta la pelicula en Guardadas
 Movies_Save.Add(Movies_Recommend[Number_Of_Movie]);
 //Remueve pelicula de Recomendadas
 Movies_Recommend.Remove(Movies_Recommend[Number_Of_Movie]);
 

 //Precondicion: La pelicula se encuentra en recomendadas
 public void Informacion_Movie(int Number_Of_Movie)
 Movies_Recommend[Number_Of_Movie].Show_Information();
 


 public void Calificar_Movie(int Number_Of_Movie, int calificacion)
 
 Movies_Recommend[Number_Of_Movie].Calification = calificacion;
 
 

As the user can requalify a movie, I did it with sum_qualifications / times_qualified

Would it be better to do it with data table?
