It's hard to say how exactly it got started (*cough* Harry Potter and Twilight *cough*), but somewhere along the line filmmakers realized that people absolutely OBSESS over Young Adult fiction. In fact, they love in so much that they'll buy two tickets just to see that last story split in half across two movies. Sometimes, that works out okay. But usually, the result is two bloated, confused films that struggle to maintain a compelling plot through the whole thing.

Unfortunately, Allegiant might be the worst of these YA offenders.
