Personally I feel like this show is nothing like Oak Island.
Oak Island they don't find... MUCH, but at least they find some historical artifacts from time to time, the 'hoax' if that's what it is has been going on a long time, there's a local history to it, even the men that have lived on the Island and worked there are very interesting. They could do a whole show about Heddon making his shaft and who he was, etc. and it would be watchable because it has a history aspect to it. On top of that, the two brothers are very charismatic, and they go out of their way to not have any Drama with anybody. It's just a cool show about not much.
Skinwalker Ranch there's just nothing there, the characters aren't interesting, nothing they're talking about seems that strange or unexplainable, the history of the ranch isn't really much.... there's just no reason to watch, very boring show to me.
At least on Oak Island you have the two brothers, and the rest of the cast all seem pretty cool if you can ignore the voice overs from the production team. The story that something was buried there is at least feasible too, then you can decide if it's still there, or was removed, or was always a hoax, or turned into a hoax, etc. it has some merit as a story. Skinwalker ranch there's just nothing interesting there....
