You've forgotten the multiple Mona Lisas in Paris. You must come and visit again sometime and I will expose you to more classic Who. There's a whole fish people ballet sequence that you probably* should not die without having seen. I'm not sure NuWho has ever been all that comfortable with the 45 minute time slot but I think it's more obvious now when the writers are, I think, more overtly influenced by the structure of classic Who.

* for a very low value of probably.
