Santa Claus coat plot hole.
One of the biggest things that I didn't like about this movie is that it ignored the concept of the first movie. In the first movie, Scott was an overbearing obnoxious man who didn't have time for his child. Putting on the coat changed him into a more loving Santa Claus. He made more time for his child and even had time to talk to the other kids in the neighborhood. The third movie forgot the coat's powerful magic. Once Jack Frost's character put on the coat it should have changed him into a nicer guy too. Instead we got that cheesy let Lucy hug Jack and melt his frozen heart business at the end of the movie.
There once was a little black kitten called Angel.
