I totally agree. My whole family thought it was such a great movie. I on the other hand in my own opinion thought it was terrible. Then my dad said I had bad taste in movies, that's just because he hasn't read the series. They didn't even mention the "Big Three" pact that they had and how Kronos was planning to come back from the pits of Tartarus. They also didn't show the Capture the Flag scene where Percy finds out he's the son of Poseidon. They just gave it to him. The didn't mention the Great Prophecy, and in the movie when Percy arrived and then left that night. It was a good couple of weeks when 'Book Percy' got a quest and left. And if you watched the deleted scenes on Blu-Ray, there are a whole lot of sexual content for a book series like this. I'm just going to stop right here before I keep rambling on and on. I just hope they give more detail in the sequel, if they ever make a sequel.
