The question with starting a new forum within NitrateVille always is, will this encourage more of the talk, by demonstrating that there's a dedicated place for it, or less, by ghettoizing it?
Generally, if discussion on something is growing, I feel like a dedicated forum on that subject will encourage it. But if it's just sort of there, not getting bigger or smaller, peeling it off may well reduce the traffic that sees it.
In this case, my feeling is that discussion of non-English language, presumably sound, films is not all that strong here, and taking it out of the most trafficked areas wouldn't help. I'm amenable to being convinced otherwise, but all in all, I just don't think it's a big area of interest for a lot of people here (partly because not all that much is readily available, as I've noted before).
