Maybe it’s that the people all feel a little too idealized?

I get what you mean. I sometimes have the same feeling. I wouldn’t say they’re without flaws per se, but they are all almost saintly at times. On the one hand it’s refreshing because it means that the usual “misunderstanding arc” that could be resolved by just talking doesn’t happen or go on for ages. On the other hand they sometimes go too far and it feels unrealistic.
