That link makes an excellent point - if we're talking about a kickstarter project that somebody will work on full-time, you have to realize that you're not just paying for the resources necessary for the project, you're paying that person's salary. Look at how much money you have to spend to make ends meet in a year, and keep in mind the potential for cost-of-living differences. That means the baseline goal for such a project, unless they're already wealthy enough to give up work for several months, is going to be at least a few tens of thousands of dollars, for a project that requires nothing but time. Adding on professional filming and editing and fending off copyright trolls and whatever other resources you need for your particular project, and you can get some pretty high prices for a 30 minute video.
Which I haven't watched yet, so forgive me for not commenting on the actual content*. If there actually isn't much, then I'd say there's a good chance she wound up spending all this time working out how best to use the money to make a professional-looking project so that people wouldn't complain about losing their money, and had less time than she expected to actually prepare content (and given how many complaints there were about how long she was taking, I can't imagine she wasn't feeling pressured to get it out faster). Using money isn't as easy as throwing it at the problem. If her starting goal was $6000, she probably intended to use that money to pay for a little more editing and general polish for a video of a kind she was making in her spare time. Winding up with $150,000 after that, you probably feel kind of obligated to go all-out, get too caught up in pursuing that, and don't have the time you thought you would to work on the content that was actually the point.
Basically, it could be another way that you can poison a kickstarter by giving it too much success.
*My food will be done by the time I finish this post, and then I'll have to eat and do homework until I have to go to work, but I'll get around to it at some point.
