Er....he's the presenter. He's an amiable face, without a moustache, who looks good on TV. It's a light programme for the mass audience. What more could you want?
Sorry, I mean no slight on the man himself, I just mean I'm not sure what kind of show he is presenting.
Is it about Bradshaw's books, and a history lesson?
Is it comparing Bradshaw's era with the modern world? (concentrating on what has changed)
Is it about modern railways? (no)
Is it educational?
Is it a compromise show which purports to be about one thing, but is really just an excuse for lots of little clips to be linked together? Yes...
Did anyone see the Dara O'Brien/ Rory McGrath/ Gryff Rhys Jones show where they "followed Samuel Johnston's trip sailing round the western coast of Scotland"? They started the show with some high-minded purpose, to follow the path of historical "adventurers", but really it was just a collection of set pieces as they meandered around (which wasn't really about Johnston's experience)...
...for me, that's what the Portillo show is like. Pleasant viewing, diverting stuff with some nice scenery at times, but not really educational, not really about Bradshaw, not really for any great purpose...
