Buffy. I was late to the series. An ex of mine, my brother, were into it in the original run. I didn't start to appreciate it until the 6th season. I also watched all of "Angel," in this timeframe, and all of "Dawson's Creek," as Pacey and Joey lived happily ever after; that is a different thread. Luckily, I digress.
A reluctant superhero. A girl who just wants a normal life, thrust into a world of demons and vampires; a tragic character. She kisses a boy, he turns out to be a Vampire. She sleeps with him, he turns evil. She gets him back, soul curse and all, and has kill him. She gets a sister, and she turns out to be the key to saving the universe; her memories of Dawn, false. She dies and goes to heaven, for saving Dawn's life (and the universe). She is torn from heaven by her friends. She sleeps with a vampire, searching for Angel, that boy she kissed. He saves her life from suicide, and a hell dimension (dancing until she burns). But, he tries to rape her. He demands a soul after failing to show his love, and is driven crazy for it. Being ripped from heaven may destroy the Slayer line, and so she turns mentor to the new generation, all of them turning on her for her dark mirror, Faith. She defeats the first, moves to Europe, and whatever happens in the comics, but hopefully, she gets that life she always wanted.
Superman just wants to be Clark Kent. That's an interesting twist for a genre thirsting for originality. At times, especially in the first season, the formula of thinly-veiled demon-of-the-week allegories about adolescence, and its pitfalls, were dated. But, as the show became less contained for larger arcs and epic tales, it still worked as allegory, but was must-see television that has aged well. Its humor, now formulaic, has influenced mine.
Seasons 2 and 6 are my favorites. Angel had the touch of melancholy, almost sweet sorrow. A satisfying villain. Season 6 tells tales in humor, and drama, about what living on the Hellmouth did to this generation of Sunnydale High students. Willow and the Trio both suffer from same disease; too much exposure to the dark arts (even Xander and dancing demon). And, the fact humanity redeems them, not more powerful magic, is perfect.
I love this show.
