I have seen too many video projects that were supposed to be non fictional either have fictional material or a misleading slant such that I would not consider it a good use of my time.
That I've seen, the problem is worse than that. A movie merely says it's "based on a true story". If you're a lawyer or literature professor, that "based on" might be correct usage - since 40-ish percent of what the movie told was true. The other 60-ish percent was utter fiction.
Meanwhile, people who saw the movie and found it decently engaging are busy convincing themselves that it was 99% true. And 99% of 'em will never bother to check.
Yeah, kind of defeats the purpose when you have to spend hours double-checking if every "fact" you just got "taught" was actually true or not afterwards...
