I wouldn’t go that far, but I noticed that many themes have bad links, like their Demo link is dead.
There are also many themes that seem to be designed for something else and then ported into Hugo somehow. And some themes simply don’t work out of the box.
Some themes seem to get updates just to stay near the top, a creation date would maybe help.
IMHO, a comment section on the Hugo theme page might help. And more filter/sorting options.
I’m not sure what’s so bad about SASS? For me it seems a mark of (on average) better quality if someone or a theme uses it. I mean it’s unfortunate that this particular library isn’t updated anymore, but I’m not sure that actually matters that much for now?
Your question is about a comment I made in Jan 2021 -almost a year ago-. I don’t think that I want to have a discussion about the merits of SASS in this forum.
You can have a look at a relatively recent discussion about SASS over at the DEV community:
