Title constraint?

This property has a title (P1476) statement constraint, which seems a bit too strict to me. Some television shows (e.g. talk shows) don't really have a title, and just get a 'Talk show x featuring guest y' label. Of course, this is different for episodic dramatised television series. I've adapted this constraint to be a suggestion instead of an issue. Husky (talk) 20:04, 7 August 2020 (UTC)

original language of film or TV show (P364)

If the item has "part of the series" and that series has a original language, isn't that sufficient?
