even though remove works great here, be careful using it in a for loop. It can cause side effects. Here is a link that explains it more with examples https://thispointer.com/python-remove-elements-from-a-list-while-iterating/

Good implementation and use of helper functions. How could you also use get_friends_unique_watched(user_data)?

what helper functions could you also use here?

Great job! I like how you thought through alternative ways to approach the functions. I added comments on refactoring your code, removing unused code, and the use of the helper functions.
