They destroyed everything

I don't think they entirely killed it, but I don't think the idea of a friend going evil had the full emotional impact it was intended to have, after having already had a similar storyline with Cole and Phoebe herself going evil.

Kind of agree with Flickerflame; I wouldn't necessarily say they killed it but still went with this vote because I didn't really enjoy what they brought to the series. While I also agree that maybe the whole storyline just wasn't as impactful as it should have been, I think my main issue is the fact that Billie's prominence made it seem like the writers had just run out of ideas for the main characters, so their solution was to throw in some new character. It just felt too random and forced for my liking.

I hated them because I felt like they were trying to force us to like these characters and the idea of a potential spin off centered around them which I did not agree with. I hated them because I felt like they absolutely did kill the final season of the show.

I don't know what to say, I hated them (Or at least Christy) but the final Showdown was epic as hell and I loved everything about the Sisters getting power from the Hallow (however you spell that)

I honestly also enjoyed Season 8 a lot because Paige, Phoebe and Piper looked better than ever lol
