Saw the trailer, has question...

I would describe this more as mix between 'Teorema' and 'Kynodontas' with more surreal elements in it.

I just saw it and the film it most reminds me of was in fact Funny Games.

Though overall they are indeed very different films.

No. It is not that irritating. This is more like absurd comedy / thriller / mystery. It can almost be called, experimental.

Hey, Soldier. Do you know who's in command here?

No, it is more subversive than that. It reminded me of Brimstone & Treacle, or The Bleeding House.
