||Every movie involving superheroes requires an origin story, and Percy Jackson & The Olympians: The Lightning Thief has a doozy. The Greek gods on Mount Olympus sometimes descend to earth to have children, you see, and these half god, half humans are demigods. They live among us. One is Percy Jackson (Logan Lerman), who is the teenage son of Poseidon and Sally Jackson (Catherine Keener). But he doesn't know this. I wonder if his mom noticed. Kind of a letdown to discover Greek gods are runaway dads...Percy finds he can think best when underwater for 10 minutes at a time. Poseidon was the god of the sea, you will recall. His best buddy is Grover (Brandon T. Jackson), who is revealed as a sort of assistant demigod assigned to watch over him. His teacher is Mr. Brunner (Pierce Brosnan), who is actually Chiron, a centaur. Give Brosnan a lot credit for wearing the back half of a horse as if he'd been doing it for years...And, forgive me, I'll have to double back to Sally Jackson, Percy's mother. How did she meet Poseidon? At the beach, I suppose. Did he reveal his true identity? If a guy picks you up at the beach and says he's Poseidon, do you say, fine, let's not date, let's just mate? Then when the bastard dumps you and disappears, leaving you pregnant, what way is that for a god to behave?...My remaining question involves the title. Call me foolish, but I don't consider Percy Jackson & the Olympians: The Lightning Thief an ideal title. The movie's original title was Percy Jackson and the Lightning Thief, which at least has the advantage of sounding less like a singing group.
