Obviously people can say whatever they want, but I personally don't see any value in dragging something down when instead I could be lifting the thing I do like up. Like, imagine going in to the job at the end of the week and saying, "Hell yeah, I love Fridays!" and some sad sack co-worker is all, "Yeah, but don't you just hate Mondays?" Buddy, why? What would be the point in being so negative, when instead you could be positive?

Or, let's give another example: I personally think "Picard" was a bad television series, which started out kind of a mess, and got worse with every season. I know other people really enjoyed season three, but I think it is the single worse season of Trek, and it's not even a contest. Now, imagine if every time someone made a post praising, some other series or new episode, I jumped in with, "Yeah, at least this one was better than season three of PIC." What am I actually contributing to the conversation?

Furthermore, I don't consider, "This doesn't feel like [X]," to actually be criticism. Critique is detailed analysis. "I don't like this because it's not what I want it to be," is just whining. Critique is an important aspect of art, but too many people confuse their hot takes as valid criticism. You brought up Shives, and while he and I disagree on a lot of things -- and agree on others -- regarding Trek, I would never say that he is not detailed in his videos. Biased, sure, but we all are. I can't speak to the specific example you gave, but I know that at least in his scripted videos he generally isn't dropping hot takes like that. Sometimes they make their way into his more off the cuff unscripted videos, but I would be staggered if he's ever released something that was solely focused on saying one show is good because it isn't as bad as another show he dislikes.
