Content filters are ridiculously easy to implement though. As long as you already have the browsing view, all you need to add is a picker that changes whatever DB query you are using to select the data.

Like in SQL all you would need to do is change this:

  SELECT * FROM movies

to this:

  SELECT * FROM movies ORDER BY rating ASC

When I built a web app for film management, that was by far the easiest thing to implement.
