Ella Purnell turns in a captivating, sinister performance as a woman pushed to the edge in Sweetpea.

ThisSweetpeareview is based on all six episodes and containsno spoilers.

In the newStarzand Sky Atlantic comedic thrillerSweetpea, based on the book series of the same name by C.J.

Rhiannon (Ella Purnell) at the reception desk in Sweetpea.

Skuse, a sheepish woman who is ignored and dismissed unleashes her inner wolf.

And this girl got fangs.

Soon her repressed rage and violent desires become a reality.

Ella Purnells incredible performance inSweetpeais as chilling as her voice performance inArcane.

Her antiheroic gradual turn to full-blown psychopathic is irresistible to watch.

She transforms a character study that could easily be one-dimensional into a human portrayal.

With a well-rounded yet overall short six-episode count, I am bloody eager for more.

Sweetpea premieres Thursday, October 10 at 8 p.m.

ET on Sky Atlantic and NOW TV in the U.K. and Starz in the U.S.
