I'm enjoying it, my DD was laughing a lot at the brother's antics (and then annoyingly asking questions as she didn't pay attention to the first ten minutes or watch the first episode). I think it has a nice feel and I like the Shelgel's despite their misplaced desire to 'help' others whilst patronising them with their adoption.
Although I've read the book I don't remember any of it - except that feeling that the house Howards End is just as much a character as any of the people. So I cant tell how faithful the adaptation is. And I'm ignoring my usual irritation with the drippy Matthew MacFadygen (dunno about my spelling there...!).
