Add Rotten Tomatoes ratings to IMDb movie and TV show pages
It's possible, but I won't add it for various reasons.
1) I have no use for it.
2) For those who do, the IMDb ratings are right there and the sample size is much bigger, e.g. The Maltese Falcon has ~60,000 ratings on RT and ~140,000 on IMDb.
3) The audience score isn't included in the RT page's metadata, so I'd have to scrape it, and I don't want to do any more scraping as it's fragile/a maintenance burden.
4) The UI isn't designed for it, so I'd have to shoehorn it into an existing location (e.g. the RT text link) or add a new UI for it. Then for people like myself who don't need it or want to see it, I'd need to add an option to disable it, and userscripts have limited/poor support for options/settings.
5) So to do it justice, it would need to be implemented as an addon (web extension), which I don't want to do, for various reasons... :-)

Is it possible to also display the audience score?
