All above mentioned are great shows! If you struggle with understanding, after school shows are a great choice. They are mostly made for kids still in school, so the vocabulary is fairly basic. A few that come to mind are... Saved by the bell, Full house, Silver spoons and Different strokes. These are older shows, but maybe one of the series will help with your language while also having fun! Best of luck in your learning. 

I loved to watch Sherlock and Doctor Who, both dont 'have easy vocabularies and theres a ton of fast talking but i just love them

The Flash. :)

I love watching breaking bad..I think is the best series.

I like to watch "everybody hates Cris" or "my wife and kids"
