I recently finished listening to this audio dramatization, available through Audible.com. It features a strong cast, including Alex Jennings as Charles Dickens himself (a role he's played before), narrating the action and weaving in and out among the characters as they go about their business. It's an interesting and effective conceit.
I wish I could say I enjoyed everything else about the program as much, but unfortunately, it had some signifcant weakenesses. There was far too little use of Dickens's own words, for one thing. I understand that a dramatization has to add, subtract, and generally change things, but even taking all that into account, I don't see why they had to use so very few of them. Nor do I understand why Eugene and Lizzie's story had to be severely truncated, and John and Bella's story badly botched. (Bella here is still torturing John almost past endurance, long after the point where book-Bella changed her ways and admitted that she loved him.) Also, there was an annoying tendency now and then to cut away from important scenes and bring the narrator in. Even if you like the narrator, that sort of thing tends to yank one abruptly and disagreeably out of the story.
I'm sorry to say it, because I had been pretty excited about this version, but I think many of my fellow OMF fans will find it, though well-produced and well-acted, far from satisfying.
