Changing the color of rating stars after watching movies and series

Hello friends
I have a suggestion for the site. Changing the color of rating stars after logging in to the account.

for example: 

Thus, each user understands the status of the movies and series that watched by seeing the page of the actors, directors and writers.
I put a sample image.

Over time, we forget what movies we have seen or not. I think this suggestion will help users to easily find the movies they have watched or not watched. 

Please vote if you like this suggestion 
Thanks
