10 Movies That WASTED Villains From Their Source Material

After Percy Jackson & the Olympians proved to be a success with young adult readers, Hollywood rightly saw an opportunity for their next big movie franchise.

While the first of the planned franchise was an enjoyable fantasy outing of its own merit, its reckless treatment of the source material proved to be its undoing.

The character of Luke Castellan was presented as a sort-of friend and ally to Percy to begin with, and then revealed during the movie's climax to have been the titular lightning thief.

While this much at least was true in the source material, the movie plastered over the character's detailed motives with a few lines of rambling, petulant dialogue explaining that he'd done so because of his daddy issues.

Not only was it a slap in the face to fans of the books, but it failed to explore the depths that the franchise could have gone to: in the books, Castellan was in the employ of Kronos, who could have served to be a villain of Voldemort-esque proportions, but instead all that the studio's changes achieved was making the movie a cheap imitation of its own source material.
