Percy Jackson and the Lightning Thief is about a boy (Percy Jackson) who finds out that he is the son of a Greek god, Poseidon. Percy has to face monsters, curses, other demigods, and a lot more on his quest to stop an argument between the gods of Olympus. The storyline is very enticing and the way that there is a modern twist on ancient legends and myths is really effective.  The actors in the film were really good, and the effects, such as lighting, sound effects, and CGI used throughout the film helped to enhance the magical and mythological feel of the film.
