Percy Jackson and the Lightning Thief. It's like watching two hours of MacAulë Culkin.
Except that it WOULD be, if the ancient greeks had Hephastus and Poseidon reversed, or if Tolkien had Aulë and Ulmo reversed, or if Disney had make Percy Hephastus' son instead of Poseidon's. FUCK YOU ANCIENT GREEKS AND FUCK YOU TOLKIEN AND FUCK YOU DISNEY FOR PREEMPTIVELY RUINING MY PUN[1].
So anyway, yeah. As expected, the concepts were pretty good, many of the translation of ancient greek concepts into modern terms were pretty nice (obviously lots was wrong, but may classic things were done ok, right down to basic concepts like "the sons of the gods trying to overthrow the gods in their turn").
But as expected, it suffered from having some random teenage guy as the main character, instead of someone interesting, and as expected the plot was a random collection of stuff. (I can't speak for the original it was based on?)
