Quite sentimental indeed. Watching this movie is always an enjoyable experience. Kris Kringle is wonderful as the Macy's Santa Claus. By telling the customers where to go to buy products that Macy's doesn't have, he provides excellent customer service. No wonder so many parents were happy. This in turn increased business at Macy's.
Kris also gets Susan to believe in Santa Claus for the first time, and in the process gets her to have fun for the first time in her life. Susan's mother's friend (date? boyfriend?) also tries to get Susan to have some fun and fantasy as well.
The best part is at the end, late Christmas morning (afternoon?), when Susan and her mother and her mother's boyfriend go to the house that Susan told Santa she wanted. This reaffirmed her belief in Santa Claus.
Outside of being the Macy's Santa Claus, Kris Kringle has a hard time in the normal world. Sometimes we should let people live in their own world and not even try to assimilate them into the normal world, just as long as they aren't doing anything wrong. Sometimes people who don't fit into the normal world are still good people, just like Kris Kringle was. Kids need to realize this.
