Nice and short at just four episodes, which - by the end - is something I was grateful for. 'No Return' is not a good show, to put it simply. There are some positives, like the (Spanish, unfortunately not Turkish, as far as I can tell online) locations & as such the cinematography and Philip Arditti puts in a fun performance, but for the most it's a slog to sit through. The acting isn't the best. Sheridan Smith is someone I like but this isn't one of her better showings, while the acting of Louis Ashbourne Serkis - son of Andy and Lorraine - isn't quite there yet; but I'm sure he'll improve ...
