Some series that I saw recently and liked were SKinwalker Ranch, Beyond Skinwalker Ranch, and Netflix's Investigation Aliens. I would give all of them 4/5. With Skinwalker Ranch, it looked like they did some great technologically advanced testing of areas on the Ranch, but at least in a few cases it looked like they were exaggerating or knowingly making things up like the time that they found a wolf-type carcass in a creek and implied to the audience that it was an extinct dire wolf carcass. In fact, it looked to me like a regular wolf or coyote should be given more consideration (I forget which, but I'm guessing the regular wolf).
