I'm writing this review after episode 2, mainly to counter some of the other overly critical reviews of Howard's End.
I loved the movie version with Emma Thompson and Anthony Hopkins, but I feel this miniseries version can explore further some of the issues and topics E.M. Forster touched on in his book; class, gender, nationality etc. Also the mirrored circumstances across the class divide and how characters deal with them
As regards race and some of the casting i.e. the housemaid and Jacky Bast, I think they were interesting choices and one Forster would have approved of. He was a fierce opponent of racism (especially anti-anti-semitism) and, to answer another question a reviewer posed, yes there were black people in Edwardian London, all part of the class struggles of the period.
The cast are all excellent, especially Hayley Atwell and Philippa Coulthard. The costumes and cinematography are great. In the first episode the background music seemed rather loud and obtrusive, but this wasn't a problem for me in episode 2. I'm looking forward to episodes 3 & 4.
To those who say it's slow and nothing happens, I'm not sure what to say. Maybe watch the other channel with 'I'm a celebrity get me out of here' on it, or a Transformers movie.
