theres no such thing as a guilty pleasure. you either like it or you dont. saying it's a guilty pleasure is trying to have your cake and eat it too -- you want to establish your taste as too good to like this bad thing, while simultaneously admitting that the bad thing is in fact bad.
I’m also not a big fan of the term guilty pleasure when it comes to media but I don’t think it’s unreasonable to say “I enjoy this thing but don’t necessarily think it’s good”
Either because it’s widely unpopular despite you enjoying it, or you recognize it as having little or negative cultural value. “I enjoy watching Law and Order even though I believe it is harmful to society”
