Personally I was a little disappointed. All the pomp and circumstance was good, and I liked some of the references, but there were a few too many self-referential bits and in-jokes. Plus, more importantly, the two biggest holes in the plot were just brushed aside in the manner of "that's just a thing that can happen now," and some of the inclusions for the sake of making it a festival of all things Doctor Who made things not quite fit properly.
I know it's only really a kids' show and it's to be expected that things just get explained away as 'timey-wimey', but I do feel they could have put in a bit more effort to make the plot a bit more coherent rather than forcing on people's rose-tinted spectacles.
