I will say that I personally really made an effort to check other submissions, after seeing Freechain, I couldn't write my post about it because I had not submitted the votes yet. There was not one other submission that I could watch for longer than a few minutes. So I personally know that I gave the others a true chance.
I can only speak for myself though :)
I was in about the same bout as you. I watched almost the whole film about Women in Kenya. That one was well made. The others ... not so much.
