The ZDF is a public service German television channel and is an independent non-profit broadcaster. ZDF is funded through a television licence and advertising and is broadcast throughout Germany. It's still considered quality television in Germany.
Prof. Dr. Guido Knopp (responsible for the Programm) is the leader of the ZDF part contemporary history and events of the day. He was the editor of the FAZ and head of the oversea part of the Welt am Sonntag (two of the three most prestigious newspapers in Germany). For the ZDF he is responsible for some docus about the NAZI-time. Königskinder was just something to recover and to have a bit fun with.
Obviously he and his team are of the opinion CP Frederik is a very lucky man that he was able to find such a classy lady from down under. I doubt that he and his team think that she is perfect though obviously they thought it's useless to repeat the most silly accusations published in some danish tabloids and repeated by the even more ridiculous and untrustworthy german tabloids (as a German myself I should know about what I'm blabbing). I don't want to say anything about some message boards. Time will tell if Mary is just a short time royal star or if she is something of real substance. Obviously the responsible people for the Königskinder docu aren't the only one to rate Mary quite high. There is a book from a swedish writer with the title "Profession Princess" (more or less) in swedish. She wrote about 14 european princesses, guess who is on top of her list.
If you feel the urgent need to listen to something not so flattering about the danish CP couple, there are also some little interviews at the ZDF website. Among of the interview partner for the danish part is Henrik Overtrup. He is the editor of S&H. This is the tabloid with the most negative articles about the CP couple. Usual when Ekstrabladet (a republican tabloid) writes something negative S&H tries to top it some time later.

Don't be disappointed! Quite at the end when they ask Overtrup if Mary is a luck for the DRF, he said he thinks that CP Mary is one of the very big successes of the DRF. A bit later he also admits they couldn't find something really bad in Marys past and that's a good thing, Mary so he said is in many ways a good choice. And don't listen to Mimi Jakobsen (who thinks that one day Frederik will make a fantastic king) and Malene Birger.
Like it or not it's your problem not Marys or Frederiks.
