Derry Girls review: A change of tack in flashback to the 1970s

A look at Aunt Sarah and Ma Mary in their youth provided a different feel for the second-last week of the series 

Mary Quinn (Tara Lynne O'Neill) and Sarah McCool (Kathy Kiera Clarke) at their school reunion in Derry Girls. 

Aunt Sarah (Kathy Kiera Clarke) and Ma Mary (Tara Lynne O'Neill) have been stealing scenes since the final series of Derry Girls kicked off, so when we heard there was a special episode on the way which would centre around the two sisters, we couldn’t have been more excited.

Unfortunately, the flashback episode has very little of what makes these two characters so great – Kathy Kiera Clarke and Tara Lynn O’Neill.
