This is such a good adaptation of Percy Jackson and way better than the movies. I have been waiting for this series to come out for years and so far have been enjoying it. I love the casting choices especially the kid who play Percy is exactly what I envisioned.
A few things I think could be improved upon,
1. Longer episodes:
Because the episodes are so short it forces the story to be told way too fast and important and amazing parts of the story and left out as a result. You have a tv series Its not a movie, so you can take time to add those little details and really develop the story and the characters.
2. More Edginess
I felt like a couple of characters where lacking for example Medusa and the Oracle. Both of these character are supposed to be spine tingling. I get that this is a Disney show however you will not offend people or scare kids if you add a little more mystery and suspense to characters. Plus it shouldn't be so easy for the main characters to defeat ancient entities.
With that being said I love the show and hope that production will get a bigger budget for season 2 and make this show truely come to life.
