The early series were enjoyable but when Jack Deam came on the show the series turned into a mess. Deam is a good actor but his character is even more of a caricature of a policeman than a 1930's vintage Ealing comedy. Not sure whether it's the writing, directing or just Deam making horribly bad acting choices. His over-the-top style seems to have influenced the whole cast who now overact badly. It's sad to see a once enjoyable series go so far downhill.
