Dutch TV series?
It's pretty much all in the title - Do you know any popular TV series in Dutch? (popular so I can find them on the internet, possibly with English subtitles) ...
If you are interested in a cartoon you should check out Alfred Jodocus Kwak on youtube. I watched this when I was a kid. Here is a link: https://www.youtube.com/watch?v=jqEPbINw5q0&list=PL3EF10E10A9956F05
I'm aware of a couple of Dutch language shows that have been on aired the BBC (so they'd have English subtitles). One was Overspel and the other was Salamander (Salamander is actually Belgian so there are little bits of French in there and the language/pronunciation is slightly different, but I still found it useful as a beginner.) Both of these were popular enough that you can find them online.
+1 for Alfred Jodocus Kwaak. It's not subtitled but as it's a cartoon and for kids it's easier to follow what's going on.
Okay well I have some titles for you here.
Gooische vrouwen, Divorce, Flodder, Flikken Maastricht, Moordvrouw, New Kids on the Block, Penoza, Voetbalbrouwen and many many more. Have a look here:
Also, have a look at the Dutch television websites.
There are two youtube channels with a Dutch TV show that is my favorite show in any language: The Mole. They have English captions on them and several complete seasons.
