Most critics like Stath Lets Flats, and the praise gathers almost entirely around Jamie Demetriou. Reviewers single out his odd, mangled way with language and his awkward physical comedy, with The Times picking out the pigeon-catching scene as a highlight. Stath is described as a real creation rather than a sitcom type, and his sister Natasia gets warm notices alongside him. There is broad agreement that the satire of London’s rental market lands, and that the small, specific details of a sheltered Greek-Cypriot family are what lift the show above formula.
The reservations are about the slapstick. The Guardian and The Telegraph, both writing on the first episode, find it heavy-handed and a little unadventurous, and The Times allows that it could grate. The spread is narrow, with nobody negative, and there is a clear pattern: the earliest reviews are the coolest, while assessments written after the series had run are the warmest.
