A lot of stuff in the Dutch langue does rarely make it pass the border... Well the Belgian border maybe (since they speak Dutch there too, at least the Northern half does). There are some Dutch films you may wanna look up. Like "Flodder" (comedy about a very anti-social family living in a high-society neighborhood), "De Lift" (horror movie about an elevator killing people), "De Cock en de moord in extase" (detective movie, about a murder on a money transporter, and famous detective De Cock and his assistant Vledder have to solve the case). "Amsterdamned" (Thriller/horror about a serial killer in Amsterdam). Or when you want something simple "Pluk van de Petteflat" may do, based on a children's book by Annie M.G. Schmidt, who is pretty similar in the NL wat Lindgren is in Sweden. There's hardly a human being in the Netherlands who didn't grow up with her work. Nice to note is that the mayor in that latter movie is portrayed by a former Dutch minister (Erika Terpstra). When it comes to children's shows, perhaps you should look up Studio 100, which is a Belgian studio (so they speak with a Belgian accent, and a few Belgian words are not common in the Netherlands), but it can still be a nice way to train Dutch. and some shows are even amusing for adults.
And if you want a very good (yet very old, so some references are a bit outdated) sitcom from Dutch origin (in the Dutch language) "Zeg eens AAA" is a nice choice, about a doctor and her family and her (somewhat clumsy) house keeper and the housekeeper's husband who is really into fixing stuff. Back in the 1980s everybody was watching that....
And at the start of every new year, we have this show called "Wie is de Mol?" A game in which 10 candidates must fulfill tasks, however, one of them is "de Mol" who secretly sabotages all tasks, and tries to turn everything into a failure. The main task for the candidates (and the viewers at home) is to unmask this "Mol". Perhaps a very nice way to train Dutch and to pain your brain trying to figure out who that "Mol" is (I manage to unmask the Mol last year, but sometimes it's really really difficult).
Want me to find more suggestions?
