The Power of Three is cancelled.
The first version lasted longer! Charmed has just been canceled by the American channel CW, and season 4, currently in progress, will be the last. No season 5 for the Vera sisters who will complete their new magical adventures on June 10 in the USA. This cancellation is largely due to discussions around an upcoming sale of the channel (perhaps to the Nexstar affiliate group) and therefore to its uncertain future. But beyond that, the audiences were not famous across the Atlantic, with an average of 650,000 weekly viewers (in France, the series is broadcast on Syfy).
Launched with the trio Macy (Madeleine Mantock), Mel (Melonie Diaz) and Maggie (Sarah Jeffery), the Power of Three revisited had been reconstituted with Michaela (Lucy Barrett) at the start of season 4.
Note that the Charmed original had lasted 8 seasons, between 1998 and 2006.
