The Mortal Instruments: City of Bones, despite reportedly having a massive fan base of book readers, failed at the weekend box office with only $9.2 million for the three days.
The film was beat by two holdovers, with 'The Butler' in first place for two weekends in a row, and 'We're The Millers' in second place. We're The Millers is already on pace to cross $100 million, which would make it the highest grossing movie in August. The Butler is also doing incredibly well, and if it holds up well, is also on pace to cross a $100 million.
However, The Mortal Instruments has disappointed because it had a lower budget than either The Butler or We're The Millers, and it has bombed with a very low opening. Also considering that YA adaptations tend to actually be frontloaded, the film probably won't do very well over the next few weeks.
Overall, YA adaptations all seem to be bombing, one after another. So what's really the reason? As a YA fan, I can say assuredly that it's because studios - instead of trying to find truly original YA adaptations that are fresh and will build a massive fan following in the future, are instead going for increasingly derivative films with schlocky storylines. The Mortal Instrument's failure will also be a setback for star Lily Collins, who has yet to have a hit on her resume - although last year's Mirror Mirror might count.
