As someone who used Netflix to help my Spanish, it probably varies a lot depending on the language. The Spanish programming with Spanish subtitles is generally pretty good.
Except for some short phrases, the subtitles were very close to what was spoken in rapid-fire Spanish.
The problem with “La casa de papel” is that is a serious multi-layered plot with complex characters that requires a lot of thinking.
“Club de Cuervos” is entertaining and no thinking compared to it. However, the constant use of Güey or Wey and “no manches” may annoy you.
