Bluepeterised is a perfect description of this very disappointing show.
I really can't believe how totally snobby and hard people are about this good little programme. It's primetime on BBC2 smack bang in the 'light entertainment' slot so it has to appeal to the masses, most of whom may need things explaining in layman's terms.
You want the nerdy stuff for university graduates and people who already have a keen interest and knowledge on the subject then turn to BBC4.
Personally I'd much rather watch stuff like this than half the brain dead stuff that's on most of the time. Bluepeter is a bit harsh. It's no worse than Dara's Science Club or an episode of Bang. Just science for the mass population.
