Despite the fact that it is hardly Charmed as in its heydays, the main plotline definitely works. The big bad of each season has always been interesting, and the Triad/Christy story is quite intriguing, though somewhat corny. Charmed tends to make up new ultimate evil/power/good constantly without likening them to previous evils/powers/goods (do I need to mention Billie being the ultimate power, totally contradicting Melinda Warren's initial prediction about the Charmed Ones being something like that). In this case the Triad - who in deed are powerful, but initially were no more powerful than Cole could take them out. The Source, at least, could only be vanquished by the Charmed Ones using the power of the entire family line combined. But, who cares, really. The Triad are working it in this episode, and there was genuine suspense when the sisters orbed into Magic School to battle them. That was definitely the highlight of this episode, although it was somewhat disappointing that Piper, as always, was able to kill one by repeatedly using her exploding power on him. Coop has got be the most infuriating new asset that Charmed has seen for a long time. Or rather since Billie emerged in her black wig. This is classic Charmed focusing on Phoebe's love life, Phoebe who has not had a boyfriend for a little while, and therefore desperately needs the Elders to actually care enough to assign a Cupid solely to restore her faith in love. I personally would have preferred the series ending by Phoebe enjoying her life as a single, for this plotline's sole function is telling teenage girls out there that they are nothing without a succesful relationship. Quoting Phoebe: 'Cole was my longest relationship, how pathetic is that?' That is just downright despicable. Coop himself is very, very annoying, probably because of his tedious attempts to lead Phoebe to her path.. eh, once again. Yawn.
Paige's wedding was rather beautiful, though also rather rushed. Rose McGowan's performance was brilliant, but I simply didn't care enough for Henry yet to feel exhilirated. The Christy plotline is the most interesting, and luckily also the main one. Patterson does a very good job, though she is a little too pretty and her hair a little too perfect for someone with her background. Billie is as always just plain annoying and too blonde for words. She is way too attached to this sister that she hasn't seen for fifteen years - she ought to be totally alienated, and yet Billie acts as protective and caring as Piper probably would if they discovered Prue being held captive by demons, as though only a relatively short time had elapsed, yet Billie has spent 75% of her life without Christy.
All in all, a well written episode with some interesting plot development. Keep it up, Charmed.
