The film tells the story of a man, Dávid, who downloads a software to rewrite reality. Of course, his friend warns him not to, but he doesn't listen to him...
So the film already sets up an interesting theme that attracts attention, but for me, the execution is even more interesting, as we watch Dávid slowly go crazy from the effects of the software, and the way he tries to hide it from others. It's also nice to see how a single decision can affect so many things. This is perhaps one of the film's best features. There are of course flaws in the film, but I was able to enjoy it despite them, as this story was able to hold my attention throughout and the movie often generated an amazing suspense. I really liked it.
