The 'Popular' episode was an early season 1 ep entitled 'Truth and Consequences'. Sam is bent on exposing the popular kids cheating so she rants on about the popular kids "privileged slime trail". Brooke's moron boyfriend Josh is self-righteous. There's a dumb food fight and the idiotic Miss Glass tries to diss Nicole by ranting "Queen Bee, buzz buzz" at her. This was a dire episode.
The 'Mutant X' episode was the season 3 finale (as well as the last ep ever) entitled 'The Assault'. The season 3 opening credits were terrible. The plot idiocy that was the Dominion/Lexa storyline brings about the end of Mutant X as we know it. The low budget kind of distracts the viewer though. One character solemnly intones: "The truth about Adam and the Dominion is far more complicated than you will ever know" and several scenes later the truth about Adam and the Dominion is revealed. The reveal that Adam is the clone of the Creator, your typical cackling, power crazed loony in a cheap wig is too much. This makes no sense. Anyway the show ends on a real downer: Mutant X are on the run and their genes are about to kill them, their hideout and jet are blown to bits and Adam's been abducted by the Creator. Adam's abduction is too easy, one security guard hauls Adam off, yet in season 1 when menaced by a new mutant out to kill him Adam kicked said new mutants teeth out. This was good, this show was my guilty pleasure.
The 'G vs E' ep was 'Renunciation'. Chandler and Henry are sent to Cleveland to make the man who killed Henry renounce his Faustian deal. This ep has Antonio Fargas as a crime boss and Nichelle Nichols ('Star Trek') as Henry's mother. Anyway Henry learns to forgive his killer and bad make up is shown. This ep was ugh.
Finally the 'Charmed' ep was the season 6 episode 'Chris-Crossed'. Chris comes face to face with Bianca, who like him has travelled 25 years into the past. In their future magic is common knowledge, San Francisco is a smoking ruin, the sisters are dead, probes seek out witches and responsible for all this is baby Wyatt Halliwell who has grown up into a super powerful evil who has demons as minions and kills anyone who opposes him. Bianca sports a leather catsuit so tight, I'm amazed the actress could still breathe. The sisters show off their trashy tattoo collection. There is much unsubtle foreshadowing of the squeaky floorboard plot device. This was a good episode with such nice future scenes like the mansion is now the tacky Halliwell Memorial Museum and it has a gift shop. The holographic Book of Shadows in the future attic is cool. Aaahhh 'Charmed' looked good before the massive budget cutbacks of seasons 7&8.
