I've ALSO been rewitching (see what I did there ) the original Charmed, specifically season 3 and 4. I am so pissed they can't use the original theme song.
I wonder how season 4 would have been if Shannen didn't leave.
Season 4 was awesome though and probably the best overall season. In my mind that was the last season. It has a perfect ending and everything. 4 seasons, 4 sisters.
