OK so I like it. Why? Well it is that intoxicating combination of dry black humour, pathos and perhaps a pleasing inevitability that whatever twist the film takes, you know it should be no other way.
I cannot fault the cast, I regretted as a kid that I did not see Katie Johnson again (I know she made many other films, but I have never collided with them), whereas Alec Guinness and Peter Sellers were often featured on a Saturday Matinee.
I am, however, pleasantly surprised at how well this film is rated by IMDb! Of course I would give it high marks, but it is very interesting to see how many other people from other nations both 'get it' and appreciate it. It is perhaps, these days, just a gentle farce with black edges where naivety blends in with irony, and I am not claiming that it makes me LoL the whole time. But it is eminently watchable and re-watchable and I would never hesitate to recommend it; indeed those who do not like it would probably not 'get me' either!
