DOCTOR WHO ON PLEX

The service has menu listings for all the New Series episodes (2005 to 2021), the Paul McGann TV Movie, and all Classical series.

However, although the 26 menu screens (one for each classic season) include all the episodes made, those that no longer exist or are not currently available to view are flagged with a message stating "This title is currently not available on any service".
