This doesn't necessarily promote a good image of Bitcoin, but at the same time as the old saying goes: "All publicity is good publicity"
I don't think "all press is good press" applies in this case when the target market we need to hear the publicity and the message are the group of people that don't often engage in "un proven" or "new" or "exotic" or "fringe" ideas.
Bitcoin is absolutely un-proven, new, exotic, and fringe to this group of mainstream people, those that represent the next level of adoption.
When they hear "drugs" and "bitcoins" in the same sentence there's only one thing they'll conclude - "I knew it was a bad thing!"
Fortunately this documentary isn't recent and the recent price run-ups this year have brought better attention via mainstream financial news sources.
