I've been learning for 15 months now I think and I can understand Netflix shows about 60-70% which is definitely enough to understand the entire context.

I started with La casa de papel because I've watched it 2 times before so I already knew the story which helps and keeps you motivated or at least entertained 😂

Also, I studies Spanish in school for 4 years but I forgot most of it.

I also do 15min of Duolingo daily, just to learn some new vocabulary.
