"Deus ex machina" can be clearly read on the side of the copier repair van at the beginning of the movie(and the trailer), but as opposed to it being the divine intervention plot device to save the protagonist, in Christmas Eve it is the basis of a story where we see God manifested in multiple ways, all from the machine.
The story is slow at times, the dialogue is fair, but has its moments. This is a story designed to make you feel connected to the people around you and maybe even care about a stranger. It is not an action movie, it is not a romantic comedy, it is not 90 minutes of CGI. You have to engage in a little suspension of reality for the given situation and spend the night in an elevator with the characters that have normal lives and experience everyday outcomes.
Not the best Christmas movie I've seen. I would have liked more more time focused on Patrick Stewart's character, but in fairness I've never seen anything where I thought it had too much Patrick Stewart. In the end I took my children(10&4yo) and had less to worry about in the content than I do with prime time television. For that I am immensely thankful and will watch this with my family again next Christmas.
