Chance of duplicate Entries

[4Learnin]

I have 1000 entries on trakt and 1500 entries on Letterboxd. If I run the script, will it ignore the already watched movies or is there any possiblity for double entries?

Currently it will not ignore them no. It will just transmit all data and will result in double entries.
The script could be modified to first call Trakt for a list of movies that are already added and then compare them to the list of letterboxd, but that would require some extra code.
Also it might be desired to transmit the same movie again if it was watched on a different day for multiple diary entries which then needs to be considered as well.

So short answer: no, but it would be possible, but requires some extra work :)
