It was no surprise that the series would be done with more respect than the previous productions. The trailers, announcements and news confirmed even more how much passion was put into this project.
The first episode was a decent start, full of energy, life, with great acting, amazing cinematography and soundtrack.
The actors are mostly great. Walker Scobell nails Percy Jackson's charm. The chemistry between Percy, Grover, and Sally was the highlight of the episode are surely other interactions will be up to the same level.
The episode structure gives the feeling of tearing the pages out of the book and bringing them to the screen, from the pace to the episode titles.
Speaking of pacing, you will hardly be bored, the feeling of a new adventure and magic is present at all times, eliminating "boring and long explanation" moments. Despite making the episode dynamic, it affects the development of the characters and the time for ideas introduced to mature, becoming very fast, resulting in apathy and confusion (even having read the books, I try to watch the series as someone who is being introduced to the story for the first time).
I know that people been saying this since the first book came out but, the first episode gave me the same vibe as Harry Potter and the Philosopher's Stone, with similar scenes such as the Minotaur's fight and the Troll's fight in the bathroom or the call to adventure in a distant cabin in the middle of the storm. It's not a negative point, just an observation.
Perhaps something that many will not agree with, but the film managed to better balance the beginning of the story with the new information that needed to be introduced, making the pace more concentrated and linear.
Overall, decent start for a series that will be a great deal in a few years.
