I haven't seen the film but I would like to - especially for the period costumes and acting. To offer some objectivity, albeit tongue in cheek, herewith another's critique -
Carlos Magalhães "Kate Winslet and Alan Rickman together on-screen again was probably the best part of "A Little Chaos." It was neither a bad or great movie, just decent enough. Rickman and Stanley Tucci came across as versions of other characters they have played. And was it just me, or were there a lot of Kate-in-Titanic references?"
