It develops the ears mostly. I could see so many friends getting the same basic understanding as well. When I went to an English Language School for High School I failed my first written test, because I wrote a letter in Germish (English words, German spelling). I worked for Cartoon Network briefly a decade afterwards and the CMO told me they hear that story often. I think few things did more for the spread of English as an international language than good movies and cartoons. German was my second language because RTL had the best american movies at the time cable TV came to my hometown (and English wasn't an option).
