‘Agatha All Along’ Review: Toil and Trouble

This review contains spoilers for the first episode of “Agatha All Along.”

Jac Schaeffer, who created the first of the Disney+ Marvel series, “WandaVision,” and has now created the 11th, its spinoff “Agatha All Along,” is not one to let an idea go to waste.

In Schaeffer’s first series, a grieving superheroine used her magical powers to create a world for herself based on classic American sitcoms. It was entertaining to watch how the show reimagined those familiar comedies within a dark fantasy-science fiction framework. (At least until “WandaVision” went off the rails toward convoluted Marvel business as usual in its last few episodes.)

Now she starts “Agatha All Along,” which premiered Wednesday night on Disney+, with another detailed sendup. This time she puts her new main character — Agatha Harkness, a dangerous witch with a half-century history in Marvel comic books — inside a parody of the grim HBO crime drama “Mare of Easttown.” Still stuck where she was at the end of “WandaVision,” under a spell that strips her powers and any memory of who she really is, the fallen sorceress is now a cynical, violence-prone small-town police officer.

You may ask yourself how, in the three years that have elapsed between the two shows, Agatha has undergone a complete personality shift, from chirpy neighborhood noodge to hardened cop. You should be more concerned, though, with why the cop-show pastiche is so disappointing — so dull and aimless that talented comic actresses like Kathryn Hahn (who stars as Agatha) and Aubrey Plaza seem at a loss.

It is a relief when that show-within-a-show ends during the first episode, apparently a quick diversion rather than an integral element like the sitcom burlesques in “WandaVision.” (Four of the nine episodes of “Agatha All Along” were available for review.)

It has set a bad precedent, though. Even when the series shifts into its actual format — a jokey, jaggedly comic fantasy quest in which a group of unfulfilled women hit the road in search of their powers — the results are mostly perfunctory. Spells are cast, but not on the audience.
