I watched that whole video on FrankoTV when it first aired. I feel the same way about it that you do Naughty-Felid and yet when I watched that particular video, I have to say that I don't blame him. It was as creepy as creepy gets He (Frank) does 99% of his videos alone. He rarely has anyone working with him.
There is this person on youtube by the name of Rick ESO who is making himself known for debunking a lot of these ghost hunting videos. He will even take you step by step and show you how they faked it.

But....he reviewed FrankoTV and to my surprise, he thinks that Frank is ligit.
The comments are pretty positive about his channel as well. Only time will tell I suppose because there was a few times while watching his videos I thought, "Fake."
