It is one of those odd coincidences that this new Irish sitcom featured the music of the Cranberries – not heard in a while – on the soundtrack shortly before singer Dolores O Riordan died. People of a certain age were saying that the series captured a period of their youth in the same way O Riordan's music did. 

Maybe you have to be Catholic to relate totally to the storyline in this week's episode but anyone will find plenty to chuckle at. The schoolfriends are about to sit a history exam but on the way get distracted and end up in a church where they are convinced that they have witnessed the Virgin Mary crying. Spoiler alert, it wasn't a miracle. 

Can this event help them to avoid the exam which they've spectacularly failed to revise for on their study sleepover? And are they going to fall for the sexy young priest who comes along to interview them before having a crisis of faith himself? And will they be found out?

It's not the most original plot in the history of comedy but the cast* pulls it off due in main to the sheer energy they exude. Everyone seems to hurtle along at a frantic pace, particularly Saoirse Monica Jackson as hyperventilating ringleader Erin, who rarely takes a breather. You are never bored and you don't have a chance to question the logic of the narrative either. The series, written by Lisa McGee and based on her own youth, might not be a miracle, but it certainly packs in plenty of charm so it does.
