I went to see the film completely unprepared, and I left the theatre rather euphoric. I liked the film because of the amiable story, the roughly-sketched but believable characters (even if we don't learn too much about their backgrounds) and the funny, witty dialog. And last but not least the surprise in the end -- until three minutes to the end I wouldn't have had an idea how to end a story like this.
The four main characters were cast exceptionally well, and the dialog -- whew! Yes, the kidnappers seem very naive (so does the manager, btw, in another way), and the words they use are heavy with cliché, but it's not a message of any kind that's new and interesting. It's what happens beyond words: I've rarely seen people in a movie talk and talk so much about convictions and ideology, but all the really important things happen inside them and without words.
So go and watch this film but don't jump on the political statements. Things might have some more layers here.
