My ratings of artists are based only on the strength of their work. To determine these ratings, I calculate my average rating for all the projects I have seen of theirs. If they are involved in a TV series but they also do film work, the TV series only counts as one project. In this way, there is an overall rating for their work on a particular TV series but appearing in or directing multiple episodes does not discount or override the strengths or weaknesses of their film catalog.
