I would have liked more about the money - the wrangling afterwards, the changing of Mrs Speakman's Will, etc. I would also have liked to see more characters - Robert Boutlour, Pamela, Sue, etc. I think they wanted to keep it simple though, and if they included everything it would have been twice as long. That would have been fine for me. Each episode isn't really an hour, what with all those adverts.
Still, I am enjoying it, and I think Freddie Fox is doing a magnificant job - regardless of whether he's actually like Jeremy or not.
