Movies with subtitles are a nice aide, but to properly learn a language, you must learn it IN the language, WITH the attached culture.

Also, please read my comment. It is not about learning a language, it is about learning new words/expressions: https://news.ycombinator.com/item?id=17627899
Unfortunately, they're no help on Netflix, because they apparently farmed dubbing and subtitles out to two different teams that came up with independent translations.
This is particularly true in Japanese, the space constraints on speech and normal modes of expression are very different.
The original English, literal meaning of the Japanese audio, and Japanese subtitles all differ significantly.
Comparing the English subtitles and Japanese doesn’t work very well for language study. Mostly you just have to look each Japanese word you don’t know up in a dictionary...
Deviating every once in a while from 1:1 dub:sub matchup is not even close to an obstacle to language learning. In fact, if anything, you hear and read two different ways to express the same thing at once.
If you depend on 1:1 matchup, I'm not sure you were consuming either dubs nor subs in a way that's all that productive to language learning. Consider relaxing and getting used to fuzzier comprehension which is necessary for transcending to conversational speed+slang.
Also, I recommend graduating to reading books ASAP to avoid languishing in the limbo of Netflix for language learning.
I find that challenging because I've focused on reading for so long that I'm severely under-developed on my understanding of vernacular, spoken language. The upshot of that being, if the subtitles and audio differ significantly, my brain handles it about the same way as if I'm watching with English subtitles: The ears get disconnected from the brain, and I default to reading without really listening.
