Whilst I don't agree with everything IC does, they have raised awareness of Kony. The problems comes when everyone that watches it believes everything IC say. I can say that I hadn't heard of him before this video and having watched this video has lead to me reading up on him both through Invisible Children and through articles criticising them and their methods.
They have released a piece detailing all their expenditures and explain that the reason they're 2 star is because they have only 3 directors not 4, and that they are audited yearly.

Basically, I don't agree with them as a whole but raising awareness can't hurt.
