@sdetweil even better, thank you! :)

Just an FYI on anyone wanting to load the Letterboxd module you will need to manually update Node fetch to Version 2 at least, and install the cheerio as these are not included on the initial npm install of the modules dependencies.

cd /MagicMirror/modules/MMM-Letterboxd

npm install node-fetch@2

once installed, head back to

cd MagicMirror/modules/MMM-Letterboxd

npm install cheerio

restart magic mirror and it should work :)
