Or wildlife documentaries that now have the last 10 minutes showing you how they filmed it. It was interesting the first time but it's silly on every one.

Mountain Monsters is my favourite of those. I don't class it as a documentary, but more of a comedy. You have a group of 'expert' hillbillies go out in a 'sidebyside' to find a legendary monster. At the start of the episode (After they've told you everything that is going to happen) they show them interview a shocked local resident. They then go into the nearest bushes and do a night investigation. This immediately prompts a frightening encounter with said beastie and the conclusion that the only way to proceed is to build a trap. Quite how this group, featuring two old men and two 'expert trackers' with 52 inch waists trampling through the bushes don't scare off these creatures is remarkable. They then build trap and spend the next night forcing them into the trap, always perfectly, then they mysteriously escape, either though smashing their way out or disappearing into the air.

Absolutely hilarious to watch, but not a disclaimer in sight about it's lack of reality. (Not) Finding Bigfoot is more respectable, they've somehow been going 6 series or so and haven't found one yet and often admit to a complete bust on their trips out.

The only Discovery shows I found watchable were Deadliest Catch & Gold Rush.

The former is very innovative in terms of shooting film in extreme conditions. One of the few series which actually makes technology work for it rather than the other way around. The other thing it has going for it is the natural drama inherent to a very dangerous job. And sea fisherman the world over are never short of character and charisma. That said, I have noticed a greater reliance on fakery over the last few years.

Gold Rush was watchable ... for .... well .... gold. Although they made a mistake getting rid of the old miner (Fred) and his dad.

Gold Rush and their continuing search for the 'Glory Hole'.

The thing about Gold Rush is the lead characters are so jaw-droppingly dumb it makes the industry look even worse than it already does.

Say what you like about the Deadliest Catch captains - they know their stuff.

Watching Todd Whatsisface stumbling from one comic disaster to the next eventually becomes tiresome.

The Curse of Oak Island one has me intrigued. I'm half tempted to just go there myself and go down myself, just to see if there is any reality to any of it.
