How? I don't think I heard that to often, but you can say you like a game and bam downvote because I don't know you don't want to use patreon or something.
I find no good translation for glazing.
I see myself saying I see the potential and predict how it ends up being, probably something good that I wish would be better.
That is probably something you can do when you have read/played or watched enough, doesn't have to end up being right.
I try to think if you can missunderstand this as negativ somehow, but even then if you don't like something that's fine too. I think there are much worse examples.
