I enjoyed Playing it Straight at the time, but it'd never be made now!
I would say the same about Holiday Showdown if it wasn't for the fact that Rich Holiday, Poor Holiday is the same concept repackaged. Depressing. Again I enjoyed Holiday Showdown at the time, but all these Channel 5 'let's sneer at the poor' shows currently being made in the same vein are atrocious and imho promote a lot of misunderstandings about poverty and benefit culture. As a society we should have grown out of that sort of thing by now.
I thought the first couple of series of Big Brother were the best, where they were still casting relatively normal human beings as contestants and the original concept of it being a social experiment was relatively intact. But Jade Goody's fame knocked all that on the head, and for years now it's felt like they have actively sought to cast the most irritating fame wannabes they possibly can. I find it difficult to watch for any length of time now that the 'personalities' are so grating. The celeb version is actually better now imho as the celebs are mostly on their way down the other side of the fame hill and not trampling over each other to be 'discovered'.
I loved Wife Swap but that definitely came with a healthy side order of snobbery (and inverted snobbery) baked in.
Always used to feel uneasy about 'How Clean Is Your House?' as so many contestants seemed to be struggling with their MH and they'd be scolded like schoolchildren by the presenters as if they were just lazy.
Does anyone remember Chained? Very early E4 offering where the contestants were literally chained together, didn't last long. I doubt things like Chained, Touch the Truck and that one where they had to compete to stay awake the longest could be made now as too much potential for damage to people's MH.
TBH though when you look at things like MAFS (which I do watch and enjoy, but the concept is definitely pretty out there!), Naked Attraction, and some of the newer concepts like Honesty Box and Virgin Island, has reality telly really evolved much/at all? I think we're going to keep seeing increasingly ridiculous (and potentially damaging to participants) concepts tbh.
