Who are the best and most realistic TV or movie sister duos?
Prue and Phoebe Halliwell on Charmed. It's a shame we only got 3 seasons of these two. They had a turbulent relationship as the oldest and youngest Charmed Ones, but their growth and development was beautiful to see. Despite the actresses' drama behind the scene, they also had incredible chemistry with eachother and with Holly (Piper).
