Plot Explanation of the Movie U.F.O. (2012)

I watched the movie U.F.O. from 2012 with jean-claude van damme.

Expecting a low budget, low quality scifi b movie i was surprised by the first half of the movie as I found it quite entertaining. In the second half the open questions where summing up and - not answered at least not that I had understood. I had the same problem with the movie D. Darko and there was a complete "official" web page explaining the plot and the background time travel theories, that where intentionally not explained in the movie itself. Is there any kind of official explanation of the plot of U.F.O, too?

Here are some tings I don't understand:

• Where there 2 alien factions in the end at war with each other?


• Why do the disguised aliens have marks to identify them?


• Why are there humans (hobo, little girl) who know about this and how can identity them even without seeing the mark?


• And so on and so on.

Is it just a bad story full of plot holes? Or is there a plan behind that (the figthts between die aliens in the end seems to hint to that).

So, the question is: Is there an official explanation of the plot?
