Hey! I've been into Buffy since around 2004, even though i never caught it when it aired, basically saved all my allowances to buy the box sets, much to my mothers despise as for I was never much of a tv person so i was allowed a tv in my room when I was a teen, Buffy got me stayed up till 4am binging -good times-
As favourites characters go... well Spike obviously , I kinda love Anya as well (not sure how most people receive her so please don't hang me), early seasons Giles, and well, pretty much all the others except Riley, don't like Riley. Didn't love Cordy on BTVS but she made up for it in Angel
As far as seasons go... kinda hard to pick one... everyone had its ups and downs, loved 2, the whole Angel/Angelus arc, Spike and Dru... ahh i love them all, just think S7 even though had a lot be liked about just needed a better Big Bad than the First, or keep the first, have Caleb around earlier or something like that.
I did ask
@HowiMetdaSlayer for help, but guessing we are on different time zones?
