Despite the two super-star actors in this film, it's very difficult to even identify an "actual" story at all!
"The Little Things" has "little" to offer...just empty drama, and a subtle reach of
unnecessary, supernaturally (undead) effect, just to look cool.
Hence, I believe that Denzel Washington starred in this film just for the paycheck.
(he's MUCH MORE talented than his role in this subpar movie.)
