Review by Cavan Gilbey
I think we all knew that this series couldn’t last forever but seeing it come to an end still feels a bit surreal. The Diary of River Song has been one of my favourite Big Finish spin-off series, actually doing the impossible job of getting me to really like River Song; a character I ended up loathing on television by the time she was playing a prominent role in the Matt Smith era. But the The Orphan Quartet feels like an appropriate end, especially with how each writer uses the theme of grief and acceptance to explore River finally coming to terms with losing her husband and parents. I don’t think this is by any means the most consistent, or even best boxset in the series, but it certainly feels like the most appropriate way to send of River Song’s solo series. I expect we’ll see her again in the future, but for now this is the end.
