I find the programme frustrating. Frustrating on the basis that I love the idea; of moving around the map among many participating collections. Its just daft in its execution. Why everything has to be presenter-led I do not understand. And its no reflection on the presenters themselves who are delivering what they've been asked to. Honestly, can't we just see stuff rather then watch people talking about stuff?
As for the target age, well it *should* be targeted at a family audience. Challenging, but not too high brow. My children are thirteen and they hate it, and usually give up before the end, because they find the 'talky bits' childish. Unlike SLOTZ which they, quite rightly, love.
