While it's certainly not the in-depth exporation of the teenage cruelty fueled by the actual FOMO phenomenon, it's still a very interesting, realistic depiction of the new lost generation of the late 2010s.
The film brings up many topics, that would deserve a movie of their own (cyberbullying, physical bullying, the untouchable upper class elite, rape, youtube prank culture, lack of empathy, a youth without any substantial vision for the future etc.), but it doesn't really go in for any of them, which leaves a bit of empty space behind. They're all very relevant and imoprtant issues, but it's more of a mosaic of problems Hungary's upper middle class teenagers face in the capital, and no coherent exploration of the underlying causes.
However the film is extremely well made, the use of mobile and computer screens is clever, the more traditional shots are gorgeous, and the acting is superb. As far as I know, the kids were not professional actors, yet it doesn't show at all. Everything is very natural, from the dialogues to the body language, it's a rare thing when filmmakers manage to stay on the ground with youth-culture. Also, András Stohl, while his presence is brief, wasn't this good for many years.
The party scene was brilliant, I've felt all the emotions you could imagine, from fun to disgust, fear and rage.
It also could've run for another 15 mins. It would've been more beneficial to see the actual consequences of the main character's actions, but the ending was satisfying nontheless.
