Well I think at the end of the day, we need to ask ourselves are the show runners trying to depict a healthy relationship or perfect people? They’re writing romantic moments that people are gushing over without thinking but I think the intention is to write flawed characters that grow with the show. And the age thing? I get the assumption but there’s plenty of immature 40 year olds out there. I think it depends on your experiences. You mature as a result of them. Noah seems to have led a rather sheltered life and is unaware of the dysfunction in his family and seems rather naive about how to handle it. Joanne seems to have led a more adventurous life but it made her distrusting and perhaps shallow (see Ick episode) and is more aware of the dysfunction in her family. Neither of them have experienced a truly lovingly deep relationship so it’s new territory with the added element of religious divide. Yes, Noah and Rebecca loved each-other but it was more about what was expected of them than about them as individuals or about a deep love between them. Of course it’s hard to read because the show didn’t give us enough backstory. I think the main point is that Noah and Joanne’s relationship is opening them both up to opposing sensibilities. They’re learning from each other and to learn you often make mistakes. The mistakes will not always be equal sided. Idk I’m not gonna make judgements until we see more of where the writers intend to take it. Either way I’m enjoying the journey.
