The personalities for characters Percy and Annabeth are so far off it hurts. I thought the big deal on this was that these actors were supposed to embody the characters so well, that looks didn't matter! Three episodes in and I'm not impressed. They made some weird changes to the story to shoehorn this snarky and combative new Percy in.
Percy starts off as whiney and clueless. No one is explaining things to him until he sounds like an idiot, and has stuck his foot in his mouth. He's rude, and not at all funny or caring about other people. Annabeth isn't supposed to be his best friend yet - but she is so hostile.
Whoever wrote the screenplays for these episodes needs to reread the source material.
The Aunty Em's storyline changes was a complete wasted disaster. I hope Disney would do better.
