Launching on Disney+ on Wednesday, September 18th with its first two episodes, ‘Agatha All Along’ looks to bring Marvel’s TV output back to a better level of success after some recent stumbles.On the evidence of the first two episodes –– four were provided to the press, but we’ll refrain from going too deeply into the others since they’re further out from release –– the first spin-off from ‘WandaVision’ will be an intriguing, magical and sometimes musical ride anchored by an ever-fantastic Kathryn Hahn.
