An attempt by Chaplin to broaden his horizons by making a serious drama in which he did not feature (apart from in a brief cameo) as an actor. I would regard this as Chaplin's first proper feature film (I think The Kid is a transitional film between shorts and features) and it's actually pretty good. It is rather melodramatic - particularly the ending which overreaches itself in pursuit of pathos - but it's engaging and full of good performances.
If I'm honest, I found this a nice change from the antics of The Little Tramp, which I sometimes find hard to warm to. It's a shame that the film was not well received at the time, as this resulted in Chaplin giving the public what they wanted and going back to the tramp for his next film, The Gold Rush. For better or for worse, his career could have been very different if the public had embraced this film.
The 'Chaplin Today' featurette on the blu-ray release is worth watching. There are some interesting comments by Liv Ullmann, Michael Powell and others which helped to contextualise the film and which made me think about it in ways I hadn't considered on my initial viewing.
