R370 The criticisms levelled at Riley always bother me intensely, and I notice they come from people who miss the point of BTVS entirely.
The best way to look at Riley is as the protagonist of a different story, a fundamentally heroic human dropped into a world where monsters are the designated defenders of a people who don’t even know there’s a war on (and isn’t that topical?). Riley is a nice & normal mortal man who wants to prevent & minimise the suffering of others and so is of a different stripe to most BTVS characters, unlikeable to anyone who sympathises with this band of magical bullies for whatever reason).
Supernatural, enhanced or immortal beings in this ‘verse at the time of BTVS (ANGEL subverts the lore later on) are universally selfish abusers and either lack or lose their humanity. That’s why there’s always someone tasked to slay them, someone who can only be a few shades better than them herself if she wants to understand & defeat them. The mortals involved in the fight against these rapacious monsters must stoop to unspeakable depths to keep them at bay. The point of BTVS is that natural mortality & humanity is a great gift & a fragile precious luxury, that only some of us get to enjoy thanks to protectors like Buffy.
Spike is a great example of unsympathetic monstrosity. He was turned at a very young age, and throughout the centuries has ever remained the same petulant entitled young man he died as. Years upon years living & walking the earth didn’t give him a shred of compassion or knowledge, or any redeeming quality whatever. When we meet him he’s literally a darksided version of the gadabout he once was, a serial killer & rapist still with a flowery accent and a codependency issue. When we leave him dying in the Hellmouth he’s exactly the same, only he has a ‘heart’ this time around so he can martyr himself for glory. He’s a monster start to finish.
On the side of the so-called heroes, there’s Willow. Magick doesn’t give her any empathy or greater capacity to learn or to love; instead it turns her into a bitter & manipulative user who tries to hurt or control those she sees as ‘weaker’. This is tastefully conflated with her ‘coming-out’ (thanks, Joss); Will was kinder, deeper, and more of an integral & intelligent person as an awkward straight technophile than as a shifty gay witch. Her ex-boyfriend Oz does a better job of trying to protect & grow the good in himself, and he’s a goddamn werewolf with literally no control over what he’s doing with at least 1/3 of his time who has to live as an ascetic just to stop himself ripping someone’s head off.
Before Riley shows up, most every member of the Scoobies (with the exception of old Giles, dead Tara, and clueless kid Dawn..seeing a pattern?) and their antagonists become fundamentally dreadful individuals at core, at least from a humanist perspective. The supernatural characters in particular are despicable because they don’t have to develop skills, INT, empathy or any other human ability, being inhumans with advanced powers who live indefinitely long lives. But the ‘super’-humans aren’t exempt; Buffy Summers herself has a season or two of profoundly cruel behaviour in her closest relationships, developing enough callousness toward her own humanity to stoop to letting Spike abuse her and then taking out her shame on her own family (but perhaps she gets a pass, being under that Messiah pressure, and all...)
Riley was despised by Buffy et al. and anyone watching for his goodness, and because he wanted to actively espouse humanity in a world that could barely hang on to what humanity it had left. That is an unfair measure of a man dropped onto a field crawling with monsters....and that’s just the ones he’s supposed to fight alongside. In another tale he’d be the guy to root for and follow and take example from. In BTVS he’s maligned as ‘boring’ and ‘naive’ and ‘pointless’ because his mission is completely different to that of his team and because he’s a totally new kind of being - a good man.
