So i was watching the season 7 episode with the blue moon, I think its one of my favourite episodes, it has a really good twist that might not have been obvious on the first watch (the girls being the monsters attacking the white lighters) and it has a nice amount of story Arc advancement for the avatar story as well, as well as nice amounts of comedy for the girls who were having PMS
lots of orbing and piper blowing stuff up as well.
But woolord you can tell they spent all the CGI budget on the elders lightening fight with Leo (which was great as well), because those monsters the girls turned into gave me N64 teas
