I wonder if this is one of the questions you were sad not to recieve answers about? Sadly Ealing comedies are not well known in America, and requires a more specialist knowledge in Britain. I must say, they're not really my sort of thing, although if asked why, I don't know if I could give a good answer. Comedy is a very personal thing, and I fear that the old fashioned Ealing greats are not given the time it would take to appreciate them.
