I don't think Harvey promised anything like monthly conversations. It was something like: "don't worry, we'll talk plenty more times."
Still I don't really get the series. If all of this is genuine, but they can't show their faces, how about demonstrating their higher capacity for sciences or mathematics. Surely that's something their freedom has afforded them. How about explaining more of the science, like can you use just some physics terminology to explain isbe interaction with visible matter.
How about confirming or denying relevance with crop circles. I'd think they would have some database that catalogues what the circle makers were doing and telling how much is or isn't a sham, or how they connect. The likes of Eltjo H hadelhoff & Lucy Pringle have shown pretty complex science behind how they form. Surely the ET's would have that knowledge and then some.
If they could capture UFO's with IR scanning, why did Farsight need to wait for the air traffic controller, why didn't Harvey guide him to there already. If it was true, they would know about it.
I'm not assuming it's all fake or all true, but there are just holes that go unexplained and if the answer is complicated politics, well complicated how. The ethos is that we're arriving at the intelligence of the free will et's, so surely we'd comprehend a bit of the political explanation as well.
