Much as Kathryn Hahn’s mischievous witch Agatha Harkness was the Mvp of the excellent WandaVision, one wouldn’t be blamed for wondering if a spin-off series about her was really necessary. Four episodes into Agatha All Along, the primary reason it exists is clear: because Kathryn Hahn is simply too deliciously devious and charismatic in this role to not be unleashed on a bigger scale.

We find Agatha trapped in Wanda’s spell — but where the Scarlet Witch played out her narrative via sitcoms, Agatha is envisioning herself as a Mare Of Easttown-esque detective in a Scandi-inspired crime drama.

The real dynamite is Kathryn Hahn herself.
