"Mammals": James Corden's decision to step away from "The Late, Late Show" may seem like a weird move — until you catch him in this six-part dramedy. He plays a chef whose idyllic life comes crashing down after learning that his wife is sleeping around. "Mammals," created by Tony-winner Jez Butterworth, doesn't have anything very wise or witty to say about infidelity, but it ends up being a terrific showcase for the lame-duck host, giving him a chance to tackle everything from tender love scenes to temper tantrums. It's not a great series, but it helps explain why Corden is ready to give up chauffeuring celebrities for Carpool Karaoke and return to being a full-time actor. Friday, Prime Video
"The English": The latest addition to the How the West Was Horrid genre stars Emily Blunt and Chaske Spencer, who mope across 1890s Kansas and Wyoming, occasionally breaking out of their funks to kill bad guys. The violence is as brutal as the scenery is gorgeous, but the dialogue sounds like the cast is reading from a discarded Clint Eastwood script. Friday, Prime Video
"Enola Holmes 2": It's hard to believe that Millie Bobby Brown is just 18 years old. In addition to her breakout role on "Stranger Things," she's co-produced another engaging romp about Sherlock Holmes' equally brilliant, but warmer sister. This time, she comes to the aid of a missing girl, based on the exploits of Sarah Chapman, the real-life hero of the 1888 Matchgirls Strike. Viewers will be more entranced with Brown's comedic timing than the history lesson. Netflix
