I'm just old enough to remember the Stu Francis era and I'm amazed by how good that was, definitely a lot of respect for the heritage but superbly modernised. The format evolved over the years of the original run, of course, and you could certainly imagine this incarnation as where it would have got to had it continued.
Nice that they have a big studio (where was it?) so they can do pieces like that fire dance - that would never have worked at TV Theatre!
I like that they are able to break a few rules - a kids' show being allowed to make references that kids won't get (Stu Francis doing the crush a grape line) is pretty much unheard of these days.
It certainly looked from the studio audience as though they got the balance right and the kids of today enjoyed it, it wasn't just a nostaligia fest for old farts.
Write that down in your copybook now.
