Now Percy and his friends have just ten days to find and return Zeus's stolen property and bring peace to a warring Mount Olympus. But to succeed on his quest, Percy will have to do more than catch the true thief: he must come to terms with the father who abandoned him; solve the riddle of the Oracle, which warns him of betrayal by a friend; and unravel a treachery more powerful than the gods themselves.
Where The Book Wins:
Well...it doesn't literally kill the Greek mythology. Yes it use it for the story but it doesn't cruelty kill it from the very first second.
Where The Movie Wins:
Hmmm...the kids in the movie are older than the book. I always felt weird when in books he kids do extraordinary things for their age. Like getting around alone, taking taxis, etc while they are 12 and no one really wondering what's going on. So from this aspect, i liked how they made them older. They choice of the actors was pretty good too. But they destroyed the book pretty much :/
Final Winner: I'm going with the book on this one. Or maybe tie cause the movie was pretty well done (special effects,acting,ost).
