Don't mean to undermine this guy's screen-scraping adventure... but if you want to use something that will tell you all the streaming services that have the list of movies, you can use:
https://letterboxd.com/dvideostor/list/roger-eberts-great-mo...
You can look at each movie to see what streaming service it's on one at a time for free.
If you have a pro paid account, you can even do:
https://letterboxd.com/dvideostor/list/roger-eberts-great-mo...
Which shows that there are 39 movies in Amazon Prime US from Ebert's "Great Movies," not 21 like this guy's spreadsheet says.
To be fair, the exercise was to scrape the reference sources... so it might just need some refinement.
Need to double check though if both lists are correct, only confirmed number totals.
Full disclosure: That letterboxd list is not mine, I just found it
