I gave it 3 stars because I think if I didn't watch the original I might light it more.
The show is not that bad if you haven't seen the original. I think for us fans what they probably should have done was make a statement that it's another universe/ dimension from the original, so we can accept the changes and the repeat of the original where it doesn't feel like it's a cheap copy. I like the characters but their problems are too similar to the original, and it feels like where you had seasons of the original show to watch the character go through a lot and develop, they seem to take everything about the original character that makes them who they are and cramp it in 3 seasons. I try a lot to watch it without the original influence it hard and as a fan when I first heard about the reboot I wanted to see piper, phoebe and page children fighting evil, I thought they would have taken one child/ grandchild from each of them to be the charmed ones.
Go watch it it's good, try not to have the original influence your take on the story of the show.
