Sometimes after two tragic events occur simultaneously, we find ourselves anxiously, though not hopefully, awaiting a third accident to corroborate the old saying, "bad things happen in threes." Suddenly we're paying more attention to the news, weighing the seriousness of each disaster in order to qualify it as the completing incident. Likely, that last piece of the triumvirate is less significant than the previous two, and it would barely register if not for our seeking it out, but it is put into the group not so much to conclude any real linkage but to fill a void that exists only in our mind's determination to associate.
Final Destination 3, a horror sequel concerned with the overzealous search for clues and connections, correlates with this idea on many levels. As a forced, unnecessary addition to the series, it lacks a satisfying relationship to its predecessors while simply rehashing the original's plot with an exaggeration of its ideas. It exists merely to fulfill a demand for trilogy.
