For me, there's just one reason. I could let go that they kinda "ruined" the Percy/Annabeth romance subplot by making it sorta official at the end. I could also let go of the age changing and the race lift. Even chiron.
Hell, the plot being changed to that of a "collect all magical items" videogame? Well, that is
annoying. Even if they added the Hydra, which was an extra at best in the second book. Oh, I could forgive the Chimera. Whatever, they can add it in another movie. No prob.
. Oh, Gods
, the climax. I was expecting something kinda
different with the fact that Ares hadn't showed up yet.
But... Oh come on. Look at both climaxes:
Book climax: Percy faces Ares, the God of War, in the middle of an open area in the ocean. This happens while Los Angeles, if my memory serves correctly, has just suffered an earthquake and is burning. Percy manages to simply injure him before the battle ends. This event influences the climax of the third book.
Movie climax: Big Bad Luke Castellan reveals himself as the Lightining Thief, and proceeds to have a superhero-esque battle with Percy. Not only is it less awesome than the book, but it also ruins several events. First of all, many people thought that Percy killed Luke, wich would end the series. Second of all, it ruins the fact that Percy is clearly a worse fighter than Luke in the books, cutting off all the tension of future installments. Plus, they didn't even show Cronos. You know, the main villain of the series?
It's just... Ugh. The climax is atrocious. Besides, it would be difficult to make a faithfull adaptation of the series. Why continue it? I mean, they can
, but the next movies have the chance of being as faithfull to the books as the first.
Really don't understand you humans... All of you slaves to short-term rewards.
