I wouldnt personally define myself as any Shipper, simply because any decent story can be written creating a good relationship, and i think all of the relationships that happened when they did, had the right impact.
Bangel intrigued me simply because of the complexities, where Spuffy did the Bad Boy turned Good, which lets be honest, we have seen before, Bangel did the Bad boy, turned Good, go Evil then be good again, the sacrifice the relationship, which granted has also been done before, but i though this variation was rather unique.
I must also say, Cangel was another face of mine, because it had a far more natural feel, genuine progression from Leader and Assistant, to Champion and Champion all the way to, in my head, Hero and Hero, both worthy of that moniker.
I could go on......so i will
Ruffy or Briley too had its moments. When i watch this show again, taking out the over the top sex, i find this is a somewhat sweet way to let Buffy down after the heavy Bangel affair.
Wara or Twillow....yikes, Hours i could spend, so all i would say is, perfect in that at times it wasnt.
Wileddy or Kenow, gotta say this, right relationship, wrong time.
Xanya or Anyder was another favourite, i felt it progressed fluidly and felt right, i was a little disappointed when Hells Bells had finished, because in my mind, Xander had not displayed enough his worries.
Spuffy, well i loved this bubbling relationship up to Tabula Rasa, when they turned Spike into a Sex pest. Then after Entropy(?) i think it garnered steam again, allowing me to like it.
also, i could go on about Fresley, Welah, Frunn, Coyle...all in my opinion perfect at the time they were.
