although i find myself exasperated as the sheer idiocy at some of the candidates and wonder how they could be doing what they're doing and not realising the problems coming - i do think its probably a lot harder than it looks - they are given a day or so to do what usually takes a team of dedicated trained professionals many months to do, when they are working with people who are on their side and trying to help - so its obvious they are going to get some stuff wrong, especially when you have a team who are actually your competition and some actively trying to make you look bad and even sabotage you.
its easy to shout at the telly but i think most people would make a mess of half those tasks.
i guess it wouldn't make good tv if they had ages and had time to iron out all the problem and make everything just right
