That Old Black Magic is not one of my favourite episodes but there are several things I like about this episode:
1) Phoebe's hair - it looks great when she has it up.
2) Piper and Leo's look into each other's eyes when Leo offers to heal her head - it shows that they still love each other.
3) Another bad witch but this time the Power of Three can't stop her - another twist from the writers.
4) Jack Sheridan and Prue's obvious attraction to each other.
5) Jack on his own.
Some things I didn't like about the episode:
1) This is the last episode with Jenny in.
2) Kyle's hair
4) The fact Piper and Leo aren't together any more.
