I am a big Netflix junkie--and the most unrealistic show they have (although most are pretty good) is Emily in Paris. I have friends in France who HATED IT and after watching it I understand why.
1) The lead character is shown running at the start and it has her doing 5.3 miles in 41 minutes (sub-8 pace). She doesn't look like she has XC experience. While she doesn't look slow, doing 7:35 pace or better isn't that common for your average non-LRC runner.
2) She says she's from the sticks in Winnetka (a Chicago suburb). It's one of the wealthiest suburbs in America!
There's a whole host of others, but I saw the entire series with my fiance and even she thought it was overrated. It had great reviews at the start.
