Isn't there a movie/series where some kid is the son of Poseidon and gets powers? Hah, somewhat irrelevant, but that crossed my mind too >_>
Poseidon has other children? Of all the things you should know about Roman/Greek gods and goddesses, it's that they have more affairs with mortals than spdude has with forums.
Now I'm still reading the book, but my buds tell me the movie sucks. Its like the Tale of Despereux . The move kept the same plot, but some characters weren't there, Some were added, most were changed(human) and alot of parts were cut out. And as always the book(Original) is better then the movie I guess Twilight would count as one of these, seeing how Edward is a bit better in the book. Sparkly+Vampires= Your gonna die soon
