I grew up watching Charmed as a kid, it filled my life with magic. As an adult, I still return to the Halliwell Manor whenever I am ill or need a pick-me-up. It is part of my life and I still love everything about it.
Granted, the first 3 series with Prue were the best and I was always hoping for a return of Shannon D in the final series - but Paige does her best to keep the trio alight. Love the cameos from Cole and Grams.
Keep airing the repeats and who knows, maybe Wyatt, Chris and Melinda will get their own series.
