It was a good article if you think synthesising previously published stuff is good journalism -- it was fairly comprehensive and appeared to be accurate.
But there are some things left open. The article says that TB is "more spiritual than religious". Yet I think that it's public knowledge that he and his family are regular church-goers. Also, for someone who's supposed not to be political, it is, at least, surprising, that he calls up a super-wealthy banker, whom he doesn't know, to give him his support. A proper journalist would have pursued some enquiries about that kind of thing.
