I know the comics are meant to be canon but I also read that Joss made a comment did he would have no problem ignoring them if he were to revive or return to the televised series. I have to say I have only glanced at a couple of issues online and in some respects I found it really departed from the spirit of the tv show and characters and some of the plot points seem really fantastical and far fetched. Buffy’s fling with Satsu, Giles becoming a teenager again?!! How do ppl generally feel?
I think the stories are terrible such as space sex with a man who murdered her Slayers. Buffy then proceeds to abandon them because Joss is bored with them. Plus the resolution to the whole Abortion storyline. Its not Buffy just a robot because Andrew roofied her rendering the whole plot moot WTF what a cop out !
You've also got some truly awful Artwork by Jeneatty. Who Joss brought back for the final season by the way. So he obviously loves it but I think it looks terrible.
Finally they basically just end the characters back in the same position to how the show ended in Chosen and Not Fade Away. Despite all the crazy things going on there's no real development
It's the same way for the Buffy verse too argubly worse because fans make excuses for the BtVS verse.That’s a problem many supernatural shows have. Death has no meaning. If characters come back to life often times, then as a viewer we stop Having fears for them because we know deaths won’t last. It actually impact the investment in the story. Though Buffy is a show that doesn’t suffer too much of this Problem ( Angel and Buffy are the two people who were ressurected.. two overs 7 years that’s acceptable I think ).
Characters would be kept around either A because the fans liked them or the B The writers liked them. The writers wouldn't even pretend to craft a decent reason why.
Spike in Out of My Mind is a Prime example. Not just Buffy but both Riley and the Government should've been after him for this. But they don't because well reasons.... Now I love Spike but to not even bother an excuse why is dumb.
Another is Harmony which stretches from BtVS in Crush all the way to Ats in Not Fade Away. Hell in that it's even played for laughs with Angel giving her a reference.
While Dawn had no story purpose post S5 and was kept around cause they liked the actress. I'm guessing it's the same reason for Tom Lenk in Buffy S7 and even Angel S5.
As for resurrection of characters it happens all the time.
Spike once Just to name 4
David Greenwalt also confirmed they wouldve brought Doyle back if Glen Quinn had gotten himself cleaned up
