Hey EvilDicey!
Thanks for posting your results and the link to your campaign! I hope you reach your goal! I looked at your numbers for your Facebook ads and I am wondering how many ads did you run? I have yet to launch my KS campaign, but I do have a good amount of experience in Facebook ads.
Facebook is all about testing. You have to test different ads against each other and see what works. We are building up our "likes" right now and so far have gotten about 120 for $50 in 4 days, totally 566. I expect that number to grow to about 1200 before we launch. One promoted post I did got close to 1000 views in about seven days and I was paying 3 cents a click. I'm not saying I'm always going to have these results, but I got these results mentioned because I tested my ads like crazy and I got a hit.
With "Like" ads, you don't have to be too specific, but you do have to be targeted. Identify who your core audience is for your project and look up pages and activities that they will more than likely be interested in. Work on your headlines and your photos. Your project seems to challenge conventional thought about religion, you could create a controversial question and tell people to "click like" to find out the answer. (make sure you run an ad like that only to pages that would be receptive, like "Free Thinkers" or fans of popular book author who does something similar). You always want to tell your audience what you want them to do (.i.e. Click "like" if you love comic books/ Click "like" if you are tired of government control/ Click here to donate to my Kickstarter campaign).
While being unable to see your ads, just out of curiosity, did you tell your audience what you wanted them to do? Did you give them a reason that is of value? Also, consider using Optimized CPM instead of CPC or basic CPM. The results can be amazing!
Lastly, I'm not an expert at KS by far. I will be asking you guys for advice very soon, but your campaign video was slow to me. I'm assuming the dryness of the narrator is intentional. If so, I would add some music or something to make it pop more or shorten the length.
That's just my 3 cents. Take what you need and discard the rest
