The issue of our day is how to interpret the title of the film, "Ninja Assassin". This controversial topic has been discussed much in the last few days. This Facebook post aims to end this discussion, and give a clear answer to this vital question. Here are the common views. After discussing these views, I show why view is a. is correct.
a. A Ninja Assassin - that is, an assassin who happens to be a ninja, or an assassin characterized by ninja like activity.
b. A Ninja's Assassin - That is, a certain ninja commands an assassin to do his bidding. This is true in the movie. But it has some problems. For example, one must insert an apostrophe to "Ninja" in order to make it work. Although, since the movie is brainless, the title may be as well. There could be an implied apostrophe or idea of possession.
c. An Assassin who kills Ninja(s) - that is, an assassin (who may or may not be a ninja) who makes it his practice to assassinate ninjas. Having seen the movie itself, it is a valid possibility. Rizo, the main character, is indeed an assassin (who happens to be a ninja) who kills other ninja (could be a collective singular noun representing a plural idea). However, this view too is fraught with difficulties. Rizo is indeed a former Ninja Assassin (in the sense of view a.) and, as such, now kills his former colleagues. So he is both a. and c.
The fundamental issue at hand is this: As a film title, what view makes the best sense? I would argue view a. makes the best sense. It doesn't have the grammatical problems b. has. It doesn't have the double meaning that c. has. Although, a double entendre may be intended, but then would the person who named this terrible film be intelligent enough to think like this? It seems best not believe this.
I would like to employ Ockam's Razor in this case. Do not multiply entities beyond necessity, or take the simplest choice among multiple options. Thus, view a. seems best.
