Sure it can. There are great, iconic, relationships in comics that are interesting to read about and examine; Spider-Man/Gwen Stacy (or Mary-Jane) is one that immediately springs to mind, or Batman/Talia Ghul.
And while I'm holding off judgement on s10 Spuffy until the end of the season I think it might be too late to do this with Buffy.
If they'd started in S8 to build her with a fresh love interest by introducing a new character that may eventually become a love interest (they did this pretty much straight away with Willow and Alywyn) but every time that was attemptyed with Buffy it was depicted as a red herring.
Her and Satsu was hammered home by everyone except Buffy as 'an experiment' or whatever, basically meaningless according to the likes of Xander and Spike. Dowling went nowhere before fizzling and was dull anyway.
The two vampires were the ones that were focused on- and even here the writing can become increasingly pedestrian. There are only so many stories than can be written about the slayer/vampire thing- and they'd all been done by S7 anyways.
I agree that the writers need to take a long look at Buffy as a character, think about where she's going, the many mistakes she's made, her increasingly grating behaviour and try and go back to basics.
In the next season Buffy, her sister and her friends need to try to figure out her place in life. No real need for 'new' romance.
But I guess if they wanted a new love interest who already had their own rich backstory, one that already has a deep connection with Buffy, one that offers fresh opportunities for storytelling, one where people could actually picture the sort of chemistry that the relationship would have...
Nah, I got nothing. 😉
