This is a Chrome extension that adds two features to Letterboxd. You can see the score & tomato type, and a button added beside the IMDB and TMDB micro-buttons at the bottom that will link you to the film's Rotten Tomato page.
Prefer Metacritic? I have a Chrome extension for that as well, view it here.
To install this, simply click "Add to Chrome" on the Chrome Web Store.

First, clone the repository.
Second, grab an API key from The Open Movie Database's website. Set OMDbAPIKey on line 1 in content.js to your API key.
var OMDbAPIKey = "YOUR KEY HERE";Next, you need to load the unpacked extension. In Chrome, visit chrome://extensions/. Click "Load unpacked" and choose the directory of the repository. It should now work.
Feel free to follow me on Letterboxd. :D
