I'm Dutch and afaik right-wing media doesn't play a role. The reason is quite simple, it's because the previous coalitions lead by the neoliberal VVD have consistently fucked everyone who isn't rich (and even some who are). Especially the crises that they've caused have completely eroded trust in the previously big parties. Some of these issues I'll lost below.

In the northern province of Groningen houses started getting damaged die to earthquakes caused by government-funded natural gas extraction. The whole country got rich of of this for decades, but when the people of Groningen needed money to repair their homes they sometimes had to fight for years to get anything.

The tax agency started incorrectly marking people as fraudsters for claiming certain benefits, which often put these people in debt for thousands of euros. This has ruined the life's of hundreds of people, yet the government initially just ignored it. While these people lost everything they had, the government seemed to do everything it could to avoid paying or helping. At some point they did start paying and pretending to help, but for many victims this was simply too little to late.

And then there's plenty of other issues that erroded trust as well. Years of ignoring "the nitrogen problem" until it was too late and lead to all kinds of issues. The farmers (who are the biggest cause of this issue) suddenly become the target of the government, which they obviously didn't like. This caused huge protests and the rapid growth of parties like the BBB and probably also the PVV. And there's also a housing crisis, where buying houses is impossible.

In short: the previous normal coalitions kept fucking up, until people seemingly had enough. There were other alternatives to the PVV, but apparently voting on a right -wing extremist who has all the ideas is easier than voting left-wing for many people here. I hope the damage stays limited, but this is truly a dark day for our country.
