crapumentary

A so-called documentary but in reality it's so poorly researched, it whiffs too heavily of bullshit, which will certainly get slated by the critics.

If credible research is gathered & produced the result will be a popular documentary, that everyone is talking about. Whereas a 'crapumentary' is badly researched & falsified, the tv equivalent of gutter press tabloid journalism. It doesn't matter whether it's true, let's just sell the story.
