This movie fails as a mystery (telegraphing portions of the 'solution' and plot from the outset) and as a Christmas movie (choose your issues with this one; they already bleeped out an expletive). Was this poor script so constantly revised that the unsympathetic characters did not know they were part of a murder mystery or a warm & fuzzy family Christmas salute? Elements of Agatha Christie literally go nowhere. Adultery, kleptomania/theft, betrayals, alcoholism, incarceration, tampering with evidence, failure to report a death, and other 'sins' of omission and/or commission end with a happy family toast. This storyline is confused and yet simplistic -- and very boring.
