>one dimensional generic female companion with a crush on the oblivious protagGame Serena
>one dimensional generic rival who can't accept that they keep losing to the protagGame Serena is a trash rival who, despite being stated to be the daughter of ace trainers, is not particularly competent and doesn't even have 4 moves on all her Pokemon in her victory road team and cries all the way through.
Anime Serena is worse because they shoehorn an entirely onesided will-they-won't-they romantic subplot into a show that it has no business being in. Ash is too young for him to be in a relationship so it means the only outcome of Serena's plot line is either her deciding she's over her crush or Ash outright rejecting her.
