Cold feet is a definitely British and not American production, which for me means that every feature of it is not designed to please instantly: You don't get punchlines every 3 seconds. Nor do all actors have the standard plastic-surgery nose (the perfect one but often with a slightly phony-looking tip and/or nostrils). Cold feet displays a lot of different types, some less glamorous than others, but all the more realistic types.
Each episode can't be seen separately. It takes some episodes to learn about all the underlying plots. The characters and their stories are told with, if not depth, breadth enough to show detail and nuances which makes the recognition effect even greater. The main intrigues are related to relationship issues and value choices in often very humorous situations - but it is far from sitcom.
