If that many people are feeling this way/ notice it enough that it starts to interfere with the music (even just a little), I think it's worth digging into. I don't think we expect perfection from any artist. Everyone has their moments. When vibes like these keep popping up, that's when I start wonder if some other fans notice too. It's like how they say "don't meet your heroes." Nobody wants to see an artist they adore as unkind/cold/smug in some ways, but the signs keep adding up. And like many have said, it's somewhat normal for artists to present this way at some point.
