The popular blend of tension, mystery and supernatural has manifested itself in this trio of new streaming shows. None of them are especially promising.
The Nevers Joss Whedon, known for his fantasy TV hits and comic book movies, created this series for HBO. Interestingly, he never directed any of the X-Men series, even though this echoes the basic premise of those movies. It takes place in Victorian London, where people, mostly women, posses abnormal abilities or exceptional powers. A group of them gathers for protection, while they also prepare to address world-changing challenges. Only the first episode has been released, but it has a rich period setting, some interesting “powers” and elements that hearken back to Jules Verne’s mechanical inventions. There are a few memorable moments, but overall it’ll have to ramp up the creativity and action for it to be HBO’s next hit. (12 one-hour episodes split into 2 six-episode parts)

The Irregulars Yet another series that resembles the Marvel mutant movies. This one is also set in Victorian London, but revolves around a group of streetwise misfits who are hired by Sherlock Holmes’ intense associate Dr. Watson. He hires them to investigate crimes in their commoners world. In typical episodic style, each episode presents a new challenge, while they also work out the romantic flirtations among them. There’s a sinister atmosphere with some creepy occurrences, but the plucky attitudes of the group gives the show it’s YA appeal. It’s not especially original, but does prove moderately enjoyable.

Them This is been announced as an anthology series with each season focusing on a different story and cast. This initial season takes place in the 50s, when a Black family moves into an all-white LA neighborhood. The rigidly-racist response is immediate, as the neighbors gather outside the family’s house in a quiet taunt. The overall pacing is extremely slow, but the underlying sense of dread never justifies the tedium. There are a few moments of hopeful horror that don’t shock and some supernatural elements that haven’t been fully manifested in the first 3 episodes. The overall evil of the neighbors is relentless and repetitive. There will be comparisons to Jordan Peele’s Get Out and Us, but the evil portent that hangs over this series never musters up the tension of those films. On the positive, the art direction and cinematography hearken back to the heyday of Hollywood 50s/60s slick artificiality. (10 one-hour episodes)
