Netflix’s GDPR dump was kind of painful to actually make use of. In particular I wanted to port my 15 years of ratings (over 1000 movies) to Letterboxd but the Netflix dump only gives title as the identifier of the media, and some titles are VERY indistinct.
Any other information, anything else, like Year of movie would have helped. Instead I spent literal hours adjusting my data in Letterboxd’s fantastic import tool.
