Yes, there is a clear quality difference between the stuff they acquire/license (some of which is quite good) and the utter dreck they produce themselves.
I wasn’t aware that „dreck“ is being used in English. TIL
What other language(s) is that word used in?
It's a moderately rare word in everyday spoken English.
“Dreck” is a German word.
I didn't know that! I got it from my mum who presumably got it from her British mum.
It's traveled fairly broadly on account of having been adopted into Yiddish - I picked it up as a very young child from an issue of MAD Magazine, and was somewhat surprised to find the New Englander side of my family very familiar with it and only bemused at the happenstance of hearing it from a five-year-old.
There is also some original content which is quite good.
