Read that you use IMDb as your source.
Yes, for the genres and for the year, we've had to align ourselves to the IMDb, otherwise the users reported differences as mistakes. For all the other data, the IMDb is only one of the many sources that we use.
Do you periodically do a total reload from IMDb to pickup changes ? How do you normally handle these type of issues ?
Yes, it's automatic: the pages are regularly reloaded, and the data checked for changes.
I've manually reloaded this movie => the wrong genre will be fixed as soon as the next version of Coollector is released.
