My old boss had multiple profiles sort of curated around topics said that it was a bit of hassle to set up but worked really well for him.
The problem is, as annoying as Netflix's algorithm is on my main profile, the algorithm to shovel shit to users it knows nothing about is even worse.
I honestly don't understand why Netflix had to get rid of the ability to literally just scan the full list of titles, optionally filtered by genre. The home screen is an utter failure, I can never find "My List" or "Continue Watching" because it's a heterogeneous mess and they jump around all the time.
