This isn't a topic about whether or not to submit a profile with another genre along with Documentary (I won't), but am curious if others do.

I think any documentary about any war that it would be sensible to include the War Genre.

Sometimes, like Sports, Music or War, if the documentary deals with such topics.  I have a number that are marked Television, but that isn't really a genre and I wish there was another field for that information.

I do, however, HATE seeing "Special Interest" as a companion genre and remove it locally every time.  It's such a vague term, and could realistically apply to every film out there.  Personally, I wish that it was defined in the rules as "anything that doesn't fit in another genre."

In profiler I have all of them as documentaries and - if availabe - with adds like war, music, sports and so on. But when my collection - and the number of documentaries in it - was groing I had to find a way to separate them, at least in a list.

So parallel to profiler I got all my movies in Excel. This had a load of reasons from average price to counting the running time and so on, and this way I simply gave the documentaries another column to show their differences like: Animals, History, War, Film & TV, Astronomy and so on.

To transfer this ideo into profiler you could simply use tags! If you then want to filter, you even don't need the genre-filter anymore but could simply use the tags to just filter all movie- or war-docus
