This is my sentence:
Users' ratings keep changing. For instance, if a user watches a movie today, he might give it 5 stars, while if he wanted to rate it after 1 year, he might not give it 5 starts because he would be watched more movies or not interested in it as he was the first time he watched it.
I feel that I make mistake when I wrote would be watched, but I'm not sure.
Tried to search bud couldn't' find the answer
