There's little doubt the writers were conjuring up memories of Back to the Future since not only are there two of the stars from that movie, but the partially disappearing ticket was central to determining if Angie had succeeded in her quest. This movie is clever in the use of those elements while putting them in a Christmas setting. One almost expects the conductor to call out to Marty.
This movie isn't focused on one central romance, although Angie's future love life is one of the threads. Angie is also hard at work on her family relationships, especially her sister and her parents, the latter evoking even stronger similarities with BttF.
Because Angie's own romance is only part of the focus of the movie, Fonseca's chemistry with her romantic opposites is not as much a factor is we usually expect, but she does have great interplay with Chandler Massey. Fonseca, and for that matter all the cast, provide good acting. The dialogue is fun and plays well to the situations that crop up. Christopher Lloyd is great as usual and Lea Thompson impresses me more in this movie than in BttF.
While the redo element of the plot is not unusual for a Christmas movie, this movie still stands out as clever and creative in story, acting and dialogue.
