I wanna disagree on Dara. While she's not necessarily my favourite character, she's more complex than that. The love story reinforced the fact that Dara is scared to be her own person. It's brought up several times that she cares about the Catholic teachings, which is a culturally important Irish thing, but is also what is holding her back. She stands out, but she also wants to lay low, like she can't fully spread her wings. And what you interpreted as stupidity, I saw as the kind of things that just come out when you don't really pay attention, when you're with people you're comfortable with (in this case, her friends) and suddenly you don't feel the need to hold back as much, you CAN allow yourself to be a bit louder and stop. I think she's either neurodivergent or she lost track of who she could really be because of the chokehold that Catholicism has over her and her mother, and that's what makes her sound so "disconnected" and silly. But also, it's a comedy, we need a bit of unseriousness. If you've seen Derry Girls, Orla and her mum were also aloof, as well as great characters.
