I do like it. Pleasant, informative family viewing. No (human) sex, scandal, violence or car chases.
However I wish they would just deal with one item in once chunk and not do this gimmicky thing where they start to cover a subject and then say "we'll be coming back later to see how Adams new turkeys settled down in their new home". We do have a span of attention that lasts more than 3.5 minutes. It's the same team that produce Springwatch isn't it. You can tell... But on those programmes the technique fits better with the format.
