I hope the show continues even if they don't find anything. Yes it can be repetitious, and the narrator is a little annoying, but that does not bother me too much. The reason that I would continue to watch, is because its entertainment. I did a book report on Oak Island when I was like 9 years old. Ever since then I have had an interest in the unexplained. I like seeing how they are going about the search, and the different theories that have come up over the years.
The people involved seem like straight up guys. Right from the get go, they told the History Channel that they would not stage anything, have fake fights with each other, etc. They were going to take it seriously, unlike so much "reality TV" these days that is anything but real. I seriously doubt that the Laginas would salt anything. The search is their first priority, and the show comes second, whether they find anything or not. It looks like the safety of everyone involved is a big concern to them. They are not motivated by greed, and it seems to be a genuine passion that makes them willing to commit a lot of time and effort to find out what Oak Island is all about. They don't need the money, so when they are waist deep in muck, it comes across to me that they don't have to be there, they want to be there. For answers. To solve the mystery. For themselves, the past searchers, for the lives lost, and also for the people watching from their living rooms.
I wish I could be there digging with them in the swamp or waving a metal detector back and forth on the beach. I can't, but I can get to see what is going on there every week on the show, at least until the season finale. Since I was a kid I wanted to know what really happened on that island. Hopefully some day I will see them get to the bottom of things. And if not, it will still be entertaining to see them try.
