I built up a similar extension to show MPAA rating on Douban and Zhihu. Though the extension is in Chinese, I setup a server to host all movies data to avoid the requests limit of omdbapi. Updating backend data frequently is definitely a hard job to do. I could guess why omdbapi is asking for support on patreon. Here's the extension link, if you don't mind I post it here :) https://chrome.google.com/webstore/detail/mpaa-%E7%94%B5%E5%...
In case Netflix is dominating your time...
This is my Free Chrome plugin that will block Netflix after 1 hour and wait for you to commit something on Github to keep Netflix and Chill'n. Other options like Khan Academy are suppported.
Main goal is to get children under twelve to go outside, jump in puddles, ride their bikes. My daughter did 10 rounds of this once, 10 hours of youtube with 5 multiplication problems each hour and eventually decided youtube wasn't worth it. It helps children to disconnect for a couple minutes and re-evaluate their summer day life choices.
Oh, well if you have someone of higher authority to enforce its continued and proper usage, then obviously that's a different story.
I was originally commenting from the perspective of the plug-in as a self-help tool where its usage and existence in the browser was determined solely by the users themselves.
In a household setting, I could see it being useful in preventing kids from spending too much time in front of the computer.
I built a similar extension for Netflix, Amazon Prime Video, and Shudder. I'm also pulling and rendering RT and Metacritic scores (when they're available). I didn't release it, I just install it locally on the devices that I frequently stream from and have it collecting dust on my GitHub.
Interestingly, I recall when hacking it together that there are quite a bit of discrepancies between the services and the release years they use for videos. One service will say that Movie A was released in 1989 but IMDB will have it listed as 1990. Release years matter for titles where there might be little or no variation between an original film, remakes, or sequels.
