We only need parentheses around conditional statements when we need multiple conditions to be finished first, then move on to another group. For example, if (not title or not genre) and not rating; otherwise, forgo parentheses. It's not very Pythonic.

This works! We can also do this all at once, too inside new_movie
| return new_movie | ||

Careful here! We are removing items from a list while iterating through it. This can result in items being skipped over because of a shift in index positions.
How best to combat this can depend. We could make a copy of the watchlist and remove from one while we loop through the other. Or perhaps we can break once we finish line 39. But then that begs the question, what if the same movie is inside the list?
Something to think about!
