I watched about 20 mins of the first episode, but found it all too painful.
It really felt to me like the parents had been 'set up' by the tv show. I've had a small amount of experience with reality shows who want to get you on board, and they are so very, very persuasive about how it will all be great, you'll get to put your message across, and what a fantastic opportunity it is. They are also very persistent, even if you refuse initially. (Though in case anyone does have this problem, we found that asking for a substantial fee usually puts them off
)
I gave up shortly after the bit where Hugo was on holiday with his parents ski-ing - it seemed like an incredibly healthy thing for him to be doing at half term, lots of outdoors exercise, having fun in the snow - and the tv interviewer was really pushing the line of 'he ought to be revising for this competition'. His parents must have thought ski-ing was a good idea, or they wouldn't have booked the holiday, and it really seemed to me like the show had edited them into appearing a certain way.
I may have misunderstood, but it seemed to me as though this 'child genius' competition was constructed entirely for the tv programme? I couldn't see how any child (or family) would benefit from taking part.
I've nothing against competitions in general, and I can completely see for example Oscar in a maths olympiad, or a chess playing gifted child loving a high level chess tournament. In that situation the child would get the enjoyment of competing, the benefit of meeting others at a high level in their favourite activity, and develop their own skills - just as a talented swimmer would compete at increasingly higher levels. But this felt much more like a 'performing seal' situation.
