Weeeellll.... DS2 gave up after episode One.
You might want to read the MN thread on it!
I live Dickens and was very annoyed by the massive MASSIVE changes to plots and the disappearance of nearly all of Dickens' words (and kindness of heart).
It depends on your DD and how 'permissive' telly watching is in your family. On the thread some year 10s and 11s were lapping it up with their trendy parents. Other posters were taken aback by the strong language and (implied) sexual content. Lots of 'social commentary was added which would make your DD remember that Dickens was a social justice warrior. However, I think the context of money lending and child poverty really didn't need altering. It's (sadly) relevant still. And there are no Fezziwigs! 
As a revision resource it is useful in the sense that your DD can discuss how much has been changed. If she doesn't know the book well in the first place, it is potentially very confusing...
Some people think Dickens would have loved it. Personally, I thought it would have been OK if they had altered the title but I can definitely still hear Dickens rolling in his grave.
Cheery it is not.
I recommend the Patrick Stewart version. Very faithful and well done.
