Season 1 was a gem. The shot where it pans over Phoebe's body as the grandfather clock begins to chime is eerily effective.

First appearance of the energy ball

So many good actors that played as demons in the series. David Carradine and Billy Drago the ones that I recognize.

I've always wondered, why was it necessary to kill all of them, just by killing Phoebe wasn't it enough to break the power of three and therefore weaken Prue and Piper who could have been easier killed in a future attack?

They gave one of their greatest resources to one of the dumbest demons

bring back the old soundtrack.. otherwise this series just doesn't work

Strategically, this scene makes no sense. Why rewind time to kill all three, when you killed one. Killing Phoebe accomplished two things; it eliminated the power of three, and it removed the barrier of a witch who could foresee attacks coming. Before rewinding time, The source simply had 2 witches, albeit powerful witches, but witches none the less. Until they find Paige, but this is season 1. So here's what should happen. First, separate Prue and Piper somehow, their powers work too well together. Next, We need to work around Piper's freezing, so we need to attack her when she's distracted; send a demon with the power of cloning, or gensis like the Kazi king or Swarm king, send in a couple of demons to attack from the front, she will freeze them and be distracted, shimmer in from behind her and stab her, covering her mouth so she can't call for Leo. Piper and Phoebe are now dead. Leo will have sensed this death and Prue will now be on high alert, so don't make any moves now, give it a few months, let them grieve and slowly their guard will be down. Now you have one witch and her whitelighter, you have bypassed premonitions giving your plans away and a witch stopping time to give the charmed ones the upper hand. However, we still have to work around Leo's orbing and Prue's telekinesis. Send demons to France to attack Leo's charge there, he will orb in to help her, leaving Prue alone. Prue's telekinesis relies on sight and focus, send in grimlocks to take away her sight. She's dealt with grimlocks before, so you have to be swift and waste no time (ironically one of the ingredients for a grimlock vanquishing potion). With her blinded and her telekinesis weakened, go in for the final kill. Now all three charmed ones are dead. Except for Paige, but she's likely still in college and doesn't know about her powers.

They should have used the 5 point palm to vanquish the time demon!

I would react the same thing when I tried to call someone's name when they're dead because it sounds and looks scary 1:33

Why would they change the special effects to something that looks worse?

It's not okay that she's dead but it's okay just summon Paige

Flawed logic. Either other sister could have answered the door

I wish Phoebe had stayed dead they'd found Paige...
