Honestly I can't imagine why there is so much hate for this episode. I love learning some back story of the parents so they're actual people and not just one dimensional secondary characters. The mammies are Derry girls too, after all. The story in this episode is a bit over the top but definitely not worth such poor reviews; many shows have filler episodes and this one is no exception although I'd argue this one ads more to the overall story. I need more characters to finish out this review so I'll just say overall this show is great, especially as a girl who is just a few years younger than the girls would be in the 1990s. Who doesn't love nostalgia even if it's from a different country?
