Your favorite Charmed era?

Charmed can be broken up in a few distinct eras. Many fans simply break it up into the Prue vs Paige years, but I believe it to be more complex than that.

Seasons 1-2: The episodes this era are episodic and there are no season arcs. Instead this era is about the Halliwell family heritage, dating, sisterhood, innocents, and the supernatural. The take on innocents is unique to the series as saving innocents is the pretty much the major plot point.

Seasons 3-4: The series attempts darker and more complex seasonal arcs here. While sisterhood and innocents still play a role, there's no doubt that the biggest role of all is the Phoebe and Cole saga. This also marks the end of the Prue years, but the themes are still common in season 4 despite her absence that it is a pretty streamlined era.

Seasons 5-7: This is the new generation of Charmed. This era is campy like never before with fairy tales, many costume changes, and baby hijinks! This era becomes mostly about the next generation as Piper and Leo's kids take center stage. It's a completely different era, trading in the gothic undertones for a fantasy magical community.

Season 8: The show is a parody, but not as fun as the previous era. Innocents, sisterhood, heritage and all the original themes are no longer present. It's a pretty sad era as you watch former heroes dread the idea of saving another person to pursue a normal life. The narrative of this season is unintentionally depressing.

So which is your favorite? Or would you break them down differently?
