Super cast, love Mark Strong, great respect for Brian Cox. All the cast was good, and the settings were lovely. It had good atmosphere, good pacing. The actress who played Anna seems to be a good actress, but I didn't find her convincing. I don't usually watch movies with pissy teenagers in them, especially as major characters, but watched this one because of the cast and the ratings. Kinda disappointed.
My other beef is that, for some reason I can't identify, and is probably just shallow, I'd have been much happier with this film if people had been able to speak in their natural British accents. I would have found the movie more believable.
