In case you couldn't tell, I'm a bit of a Greek mythology freak. (For the record, Cassandra is a woman that Apollo fell in love with. He gave her the gift of prophecy. When she did not return his love, he placed a curse on her. No one would believe her predictions.) Needless to say, I was intrigued when I was the commercials for the movie. Unfortunately, I hadn't heard of the books so I wasn't able to read them ahead of time. I went in with an almost-clean slate.
I absolutely loved the movie. The graphics were awesome. My favorite was when Percy and his friends were fighting the hydra. The writers didn't mess with the gods to make them more politically correct or fashionable. For the first time in a long time, I've seen a movie that actually makes me want to read the original source material. Luckily, my local library has copies of the series. I haven't heard anything about the next book - The Sea of Monsters - being made into a movie, but I'll be crossing my fingers!
