I kind of understand those people who say this film has some flaws. Yes, maybe it wasn't flawless. Sure, there were some mistakes in it. But other than that, it's an amazingly great movie!
Ferenc Szilágyi's (or in Hungarian, Szilágyi Ferenc) performance was terrific!! And by the way, I think the other actors were pretty good too. Boris Skalsky's music was also fantastic and the story was brilliantly constructed. The direction was good, and the cinematography was pretty amazing... for the most part.
So actually, it was an amazing film and it was really enjoyable for me. If I had to talk about "Valóság.exe" briefly, I would say that it's a very well constructed and unique horror film.
