I've really liked Ncuti as the doctor, I've liked the companions as well. I've liked a good bit of the overarching mysteries of the last season and this one. But as someone who grew up watching starting from Eccleston, and then went back to watch the original series, the only part of the new season I really dislike is the front and center focus of "Magic" villains. I understand that this was done a bit in the original series as well, but I disliked it there too. It really cheapens the entire narrative when the doctor can somehow overcome what are essentially gods with an almost unsurmountable level of power that doesn't have to be rooted in some sort of scifi explanation.
Obviously this is a personal opinion, and it does seem that the target audience has shifted a bit more mainstream (not that it was super niche before, it's just that stories now feel very surface-level), it just saddens me that a show I liked has taken a turn for the worse, narratively speaking. I'm still mostly enjoying these seasons, and their more grounded stories feel pretty similar to the 2005 series.
Vast majority? Eh, maybe. I watch a crazy amount of anime, and I've only had a few of the shows I'm interested in pull that, and typically I just don't continue watching. The one trope that I really dislike that gets shoehorned into almost any anime is the over-infatuation of a sibling. I'm not talking incest or anything, but for some reason there's almost always a character who is obsessed with their sister/brother, and it weirds me out. Not enough to stop watching if the anime is otherwise good, but definitely enough to stop watching if the anime is just soso.
Now, oversexualization of adult characters? That's almost unavoidable. I tend to just ignore it, until I show an anime to someone who hasn't seen anime before and then I'm hyper aware of it. That's why when introducing people to anime I usually pick Death Note or Fullmetal Alchemist. These anime have a good dose of the anime goofiness, but very little fanservice, almost none.
