As a writer, I can say pretty much that both Shy and Dark Wind are right.

[b]Remember:[/b] A book, or a film, or a game, or other piece of narrative fiction is up to the individual person viewing it to interpret. A story can be anything you want it to be, and the most powerful stories very often leave it up to the viewer how things really, truly... End, or what they meant. Meaning is as subjective as faith: This film can be seen in a pro-LGBT light and that's a true way of looking at it, it's completely valid. So is the view that it's just a message about being pro-who you are. Whether you back that up with evidence to try and strengthen your case based on how you saw it or not is, also, entirely up to you.

Now if an author really wants to, they can come in and debunk something, state how it is, however, you'll notice this doesn't happen all that often, because most successful authors understand the magic of the viewer's imagination. It's one thing to tell someone what something is, it's another power altogether to have someone draw their own conclusions from what you have created and in doing so make for themselves an entirely new experience you may or may not have intended.

The penultimate goal of fiction is to be either informative or entertaining. Anything and everything else is secondary. So someone coming to their own conclusions about a film's message, whether it's a variation on the overall message, a message within a message, and so on, is just as legitimate a view as taking the work at face value.
