Why does Dutch have a reputation of being difficult?

The Simpsons exist in Dutch by the way, the film was aired in as well (Flemish) Dutch as in English here. I'm not sure the serie has been done in Dutch, but I've read about the idea rising. People are very biased against overdubbing brilliant voice acting.

Here's the Dutch version from the Netherlands (bad example though):

Also exists in our variant.

The original is more popular here.

Matt Groening himself says the (European) French dubbing is his favourite.

Marge's French voice just cracks me up!

Yes the french dubbing is an incredible success, and the voices not so different from the american ones. Only maybe Crusty is really different (i prefer though the french one, because of the habit).
