Season 3
Just finished season 3 and i absolutely loved the R& B episode and the relationship between Randall and Beth. Yes, it's not ideal but I felt that the writers trully conveyed modern couple problems, the actors have a really good chemistry too. I also enjoyed that the season had subjects relatable to many people: decision to have a child, hardships of getting a job, figuring out what you want to do in life once you reach a certain age, pregnancy, having a premature baby.
What i didn't enjoy this season was the war scenes, i just felt they were missing some depth.
