The Outlaws

BBC1, 10.35pm

Stephen Merchant's delightful comedy has had its fair share of dark moments, and another seems to be looming in the final episode when Christian's archenemy begins to close in, forcing the young man to disclose secrets about his troubled past. Meanwhile, Frank (Christopher Walken, above) may have finally won over his daughter – here's hoping he doesn't blow it by doing something he may live to regret. ★★★★☆
