“I’m so f**king sick of peace. It’s all anybody ever bangs on about.”

The five beloved Derry Girls – including honorary member and ‘wee English fella’ James – are back on Channel 4 for their third and final season, their teenage trials and tribulations set against the backdrop of The Troubles in the 1990s.

But as the permed Michelle says, the girls have more important matters to worry about than peace talks – namely their GCSE results, or which film to pick out next at the local video store. (Michelle’s vote is for Braveheart, which, judging from the cover, is clearly about a Scottish drag queen.)

Everything that made the past two seasons of Lisa McGee’s comedy series magic is back, from the specificity of life in the ’90s and attending a convent school, to the ongoing feud between Erin’s Granda Joe and his long-suffering son-in-law, Gerry. The new addition of Granda Joe’s homicidal ginger cat Seamus – the apple of his eye and the bane of Gerry’s existence – does little to put out the flames. 

The scene-stealing, eye-rolling Sister Michael is also back, on crutches (“You should see the other guy”) and merrily sowing seeds of doubt amongst her anxious pupils ahead of exam results day. The only thing that can bring her down is the earnest Father Peter, now sporting a ponytail. 

But most of all, the show’s magic comes from its evocation of teenage life and friendships, our adolescent heroines (and hero) caught up in their sheer, overwhelming passion about everything, whether that’s a new crush or favourite song, or the absolute certain knowledge that failing your GCSEs will spell the end of life as you know it.
