The German fantasy market leaves a lot to be desired, with most series just being cash-ins on whatever is currently popular on the English market.
Is anyone else astonished that the country which gave us Richard Wagner can't produce good fantasy fiction?
Germans are good technicians who can extremely optimise on a given task, rarely they are willing to go in an unconventional way. Wagner as a composer was not as good as it seems, but he spread the very important term of "Gesamtkunstwerk" (it was named in 1827 for the first time and repeated by Wagner in 1849). And his Oper becomes a Gesamtkunstwerk, by each element contributing to each other and complementing it (in his family there were many different artists and not only musicians). Only in music germans are above average, but are way overshadowed by UK and USA musicians.
In film they are below average and Fritz Lang is long dead. The only interesting german films are the Nazi films and everything else is dominated by quotas and awkward elements that do not belong together.
The german literature ( after the WW2 ) is below average. Günter Grass has wrote only one exceptional book: Die Blechtrommel. And many germans question why he has received the noble prize in 1999.
Where germans were due to their ability to optimise were also very good in philosophy. Germans had their very great time, but nowadays the produce art from mediocrity to bad quality in music, films and literature.
Perhaps the WW2 has cost the germans more than they thought. And if you compare works or artists, then you should do in the same department, like writing. And the the sentence would be ...which gave us Goethe and Schiller can't produce fantasy fiction.
