Suggestions for a sequel, reworking?
The true and honest answer is that directly repeating your ideas and conclusions isn't going to work well. The original idea--introducing a newcomer to Christian Chandler--was done and done pretty well.
I don't think edits and clarifications really deserve a sequel. A second draft that addresses some of the factual errors would be an obvious upgrade...but I suspect that redrafting the documentary isn't quite what you had in mind.
---------------------------------
There are certainly lots of ways for a second documentary to go:
How and why did Christian W. Chandler become a repeat offender lunatic tomgirl? The prior documentary largely excluded Bob and Barb ("Borb"), and completely took Chris at his word.
Who are the Trolls? Alec Benson Leary and Thetan might be willing to help with that and offer some insight. I'm not sure if you'd get a holistic perspective, but I think you'd be able to find a few people to answer those questions--and I strongly suspect you'd learn a great deal from that direction. In a world with shrill shills out to swindle and play the victim card, giving form to the amorphous "Cyberbullies" might be very positive.
Go to a more general lolcow analysis. Jace Connors and Deagle Nation, Brianna Wu and her Victim Industrial Complex, Gloria Tesch, Nick Bate and so many others--the Kiwi Farms has started to gain more information about the most dysfunctional people on the information superhighway. I'm sure there's a doctorate in sociology to anyone who can figure out how to shift society subtlety to help these people at a reasonable cost before they decide to go on a shooting rampage in Halifax.
Promoting a solution. Risky. Chris won't listen; and while Chris is very likely to be receiving some kind of treatment in the near future, it will not be voluntary or desired by Chris. The rest of the world might at least listen to what you have to say, if its interesting enough and reasonable enough to consider.
The obvious problem with promoting a solution is that you wander into the realm of politics. Should Chris be institutionalized? Welcome to a long debate on the role of mental health services that people don't want the government to provide. Should Chris somehow be compelled into some kind of Conservatorship? Barb is staggeringly negligent and defective in her own way. Should Chris have been taken away by Child Services? Oh boy...
A well written "solution" may well change the world in a small way. Much more likely, you'll offend the 30% of people who disagree with the idea by ideological or political reasons--and it's hard to remain liked after you've offended those individuals. Don't get into politics unless you are ready for that 30%, and I'd suggest trying something else instead.
Go Deep. Focusing heavily on one aspect of Chris' life or one saga might be very illuminating and raise very different questions and concerns than the original documentary. The obvious problem is that Chris is an unreliable narrator, people who Chris has screwed with don't necessarily want to come forward to tell their story, and Chris has legitimate reason to lie. A
Sonichu documentary would probably work, given the material that's on the Cwcki. It might be possible to turn
10/28/11 into a documentary, given all of the documented motives and eyewitness reporting. Otherwise, there's going to be a lot of gaps in coverage--but you've proven yourself pretty resourceful at filling some of those.
-------------------------------------------------------------
Without at least a general idea of what the framework is going to be, it's kind of hard to offer more advice than that. Pick a focus of some kind to go beyond the documentary, and I'm sure a workable draft can be made fairly quickly.
