It is difficult to choose a favourite season. Each has had its highlights. I suppose the most recent is easiest to have in memory and I did love The Philadelphia Story because of its flashbacks. In these scenes, Kate and Kevin, and Rebecca, are still reeling from the death of Jack.
You see the time Rebecca's going through the house with the realtor, Jack's voice in the distance. In the current time, although Rebecca is now married to Miguel, she still carries around a piece of Jack with her every day. So you get the current situation and the past situation, which are both compelling.
