It looks like you're creating credit pages that haven't been worked on before. Instead of filling them in with random letters, put the placeholder in like you did for The Emoji Movie/Credits.
As an alternative, you could work on other pages that need more information. Whittling down the list of pages we need helps, but adding more information and substance to existing pages that need it would help even more.
A lot of the edits you're making are incorrect or cause other problems, such as when you removed the references list from a page. I think you should focus on making other kinds of edits from now on. If you watch a movie, spend time updating the page for that movie to help describe what happened in it.
