I can only repeat what I said on multiple similar shows before: I am a firm believer that there are other intelligent cultures somewhere in the universe but I don't think even one has ever been here.
This is just another docu where people claim to have evidence that is ultimately circumstancial and inconclusive. Most of the time they say it's unexplainable (to which I can agree) and therefore it has to be from outer space (to which I don't agree). Now, I am not ruling out the possibility but for me there isn't hard, undeniable proof.
Plus the style, like almost every documentary I've seen on this topic, is leaning very much towards over dramatizing, conducting interviews in abandoned warehouses f.e., which ultimately is another thing that makes me doubt many things.
Maybe one day we'll have proof one way or the other. And I for one are very much looking forward for that happen. That there'll be a day where there is no shred of doubt left. And I would accept it even if we could proof nothing of it was from another world.
But we are not there yet.
