This is the best Christmas movie I've seen for many years; Best since "The Christmas List".
I thought all four of the principal actors demonstrated great personalities consistent with their characters and the storyline. Situational dialog between all character was great; and included many enjoyable scenes of Christmas spirit, sentiment, and humor.
I'd strongly recommend viewing of "Mary Christmas" to become an annual holiday season tradition for everyone; especially busy and lonely people, plus families large, small, or fragmented. It will remind them of hopes (past and present), and brighten their spirits (present and future).
