I like 'A Touch of Frost' but ...
Inspector Frost is very moronic. First he gets one of his inspectors killed by going in to confront a murderer alone, then 2 episodes later he almost gets his dog killed by doing the same thing. He never seems to learn from his mistakes.
But then the police officers in Denton seem pretty incompetent. Criminals trying to escape often make them look like keystone cops, with their inability to stop someone running away even when the criminal is running away in the actual police station.
