So it's making fun of Mormonism, but it's created by two of the most talentless idiots in the world? That probably makes it more likely to be just be insanely stupid and not funny.
It basically swept the Tonys. I don't see how somebody who likes Seth MacFarlane can call Trey Parker and Matt Stone talentless idiots, even though I'm not hugely fond of them myself.
Keep in mind that BRTD obsesses over small things - he essentially disagrees with a couple of things he saw in South Park, so therefore the creators are right wing hacks with no talent.
