'Charmed' Season 2: The Halliwell sisters need to be on the CW reboot, and here's how the writers can make it happen
When the 'Charmed' reboot was announced many fans of the original show were displeased that the show would "start over" with a new set of sisters instead of bringing back the original Halliwell ladies. The original show ran from 1998 to 2006 on The CW's predecessor, The WB. The Power of Three belonged to the Halliwell sisters, Prue (Shannen Doherty), Piper (Holly Marie Combs), Phoebe (Alyssa Milano), and Paige (Rose McGowan). When Prue was killed by a demon, Paige came into the picture. On the reboot, we have the Vera sisters: Macy (Madeleine Mantock), Mel (Melonie Diaz), and Maggie (Sarah Jeffery).
While the reboot did better than expected, it has a long way to go before coming close to the original in terms of content and fan reaction, but it's not impossible. One of the ways the reboot could do this is to build a proper connection to the original show that created a whole new universe and started it all. Even if the makers of the reboot are unable to get the original actresses back (and they shouldn't straightaway without building the bridge), the writers could introduce the Halliwell stories into the reboot.
The reboot made a reference to Melinda Warren -- who, in the original 'Charmed', was said to be the founder of the Halliwell line -- and it could imply that the Vera sisters are also descended from her and this could be the starting point. While the first season may have made it seem the Vera sisters are the first in its universe, it wasn't something that was definite, meaning the writers could bring in the Halliwell stories gradually. And with the Elders gone in this new iteration, it makes sense. The Vera sisters are supposedly left in charge, but these are three women who just learned they are witches. They are definitely going to need guidance and perhaps learning about the Halliwell sisters will help them take up the mantle.
All this, of course, would pave the way for the return of the Halliwell sisters -- which would be nothing short of a miracle, if pulled off -- and would catapult the show to something it wouldn't have even dreamed of. Imagine Piper, Phoebe, and Paige showing up as the new Elders -- quite unlikely, but this could make the new 'Charmed' the greatest reboot in TV history.
