Still does CBS really need a Charmed reboot? Murder, She Wrote? Knight Rider and Bionic Woman made some sense, but others just ended and others still don't really have a fan base. What fanbase do you think Murder, She Wrote has? They are all dead.
Since I'm of the opinion that Charmed
and Murder She Wrote
didn't need to be made in the first place, you're asking the wrong guy.
