I ran into the same problem as you. I was really confused why ratings i had in my .nfo files would not just show up in Kodi
The problem with most skins is that they use Skin Helper Service to get all the ratings, they don't just read them out of your Kodi DB.
what happens in the background when you add a new movie/tv show is the following.
SHS calls Metadata and Utils Service which will use the OMDBAPI key to get all the possible ratings from OMDB. then those ratings will be saved in your SimpleCache.DB.

I've had no issue using the versions provided by the Bingie Skin.

Thanks CK77.
In the process of Rescraping everything in Kodi
It was needed anyways as there were some dual nfo's causing my kodi to become confused.
I have to say though that tmdb ratings are there but RT ratings are just non existant , maybe i saw 1-2 movies where it was displayd.
So partial success.

it takes some time for the ratings to show up, give it a few hours.

OK 
BTW  Could you maybe discuss with Dan to incorporate maybe the omdb ApI within Ember  if at all possible ?
