The premise doesn't feel like it will last long before exhausting itself, and the first few episodes weren't particularly funny, but there are things Cuckoo has that rescues it from the doldrums: like a fantastic cast and oodles of charm. Samberg (a major star in the US, best known for appearing on Saturday Night Live) lights up the screen whenever he's around, and overcomes the fact Cuckoo's a rather thin caricature of modern-day hippies; while Davies is doing a superb job as the exasperated father desperate to get rid of his son-in-law without breaking his daughter's heart in the process. Davies had a memorable role in The Inbetweeners as the sociopathic teacher Mr Gilbert, but Cuckoo feels like it's truly announcing him to the world of sitcom. He's really good and has a fantastic dynamic with Samberg, which was largely responsible for the brilliant third episode where Ken and Cuckoo finally managed to bond thanks to recreational drugs.
I just wish Cuckoo was a touch funnier without relying so heavily on the performances of Samberg and Davies to raise smiles and pull it through, but I'll keep watching because it's well-made and has undeniable heart.
