The movie / documentary ... should have been shown in cinemas, at least in a majority of countries; however, there are always exceptions to that last condition ... but definitely there should have been more than a video or tv release.
We should draw a line somewhere and that is if has (V) or (TV) behind its name on imdb then it is not allowed. When you make exceptions others will have his or her exceptions and then you get movies that were made for television in like say Germany or Holland, which even most of that country even never seen. I think with this rule (how it is now) there are still lots and lots of movies, and even more shots.
Agree with Krukev, there are enough theatrical movies... I have to create quite every movie I post in the database, and I've so many shots of movies that are no yet created that I would need years to post them all !! So no needs of TV or V movies here, and no exeptions... Just try to watch something else than the 200 ou 300 movies that occur "ad nauseam" in the NS...
