Amazing honestly, i love the representation we get in this, as well as the small details from the books, its way more accurate already than in the Movies.
The casting is done super well even though it might not be as exactly in the books but the actors play their rolls so well i don't mind they don't all look exactly as told in the books. We get the true personalities of the characters and to me thats what matters most.
A lot of people say its fast paced but it has way less cut off's than in the movies and really follows a storyline instead of pasting scenes together it feels like it's an actual journey.
The cinematics are also something which is added beautifully, every scene looks amazing and feel like you can see yourself in it.
It stays true to the books as much as it allows and seeing as Rick Riordan is helping out i have huge trust this will be the series this fandom much needed and wanted after years of disappointment from the inaccurate movies.
