Just out of curiosity, what did you like about the reboot?
Well, it had a lot more substance and less shlock than the original. The original was trying to be a
Buffy knockoff without the intelligence, but the remake was smarter, more serious, and richer, telling stories exploring feminism and queerness and ethnic identity and social justice, and had some potent and nuanced character drama. It even took a more global approach to its magic system, rooting a lot of it in non-European mythology and cultural heritage, which was interesting and fresh. It largely fell apart in season 2 when a new staff took over and semi-rebooted its storyline, dropping most of the cast and plot threads from season 1 and becoming shallower and cheesier, but it recovered in seasons 3-4 and became a good show again, though never quite as good as season 1.
Not that season 1 was perfect. Its feminist perspective took a major hit right off the bat in the pilot when the sisters' Whitelighter, the main white male character in the show, literally abducted the sisters, tied them up, and explained their true identity and destiny to them, rather than having them discover it and empower themselves. But that was a single mistake and the show quickly moved beyond it.
Although for me, a large part of the appeal was that it co-starred Madeleine Mantock, whom I quite liked when she was in the Greg Berlanti remake of
The Tomorrow People on The CW a few years earlier.
As far as being "derivative" goes, I found it interesting how different it was from the original, using the general concept but building it around new characters and reimagining the mythology of the series in new ways (for instance, completely redefining the nature of Whitelighters). There seems to be a trend in recent years of shows like that, reboots that take the general concept but start over with completely new characters, usually centering on people of color when the original casts were white -- The CW had
Charmed, 4400, and
Kung Fu, and Netflix did that reboot of
One Day at a Time with a Latine cast. Plus there's Apple TV+'s reboot of PBS's
Ghostwriter, which has little in common with the original besides the title, but both versions have centered on diverse casts. Oh yeah, the 2009
V remake on ABC also counts as a same-premise-different-characters remake, but with little increase in cast diversity.
