Captain Marvel had much the same sensibility as Tintin too- innocent orphan boy reporter hero, whimsy, some full blown elements of fantasy - super intelligent Snowy is more than matched by hepcat Tawky Tawny for example.
It's the ligne claire flaire that's been missing ever since too. It will take more than loony tunes officianado Jeff Parker to create a true modern Captain Marvel. Personally I'd hand it over to either the Rainbow Orchid or the Tazo the Public Servant guys.
