import of csv from Criticker
It seems as if it is not possible to import the csv from the Criticker website?
Is it possible to adjust something in the file to make it compatible with TMDB?

There are file templates here.

Some users do the adaptation using a spreadsheet.

The CSV file must necessarily have the IMDB ID of the movie.
