There are many succesful young adult movie franchises. Twilight, The Hunger Games and Harry Potter are just a few. But for as many succesful ones, there are just as many franchises that did not work out exactly as they wanted them to. Here are just a few. Hopefully the upcoming 'The Darkest Minds' will have more success.
1. The Mortal Instruments (2013)
Now we have 'Shadowhunters', but there was also a movie based on 'The Mortal Instruments' series written by Cassandra Clare. This movie didn't do as good unfortunately. The movie starred Lily Collins and Jamie Campbell Bower. I personally enjoyed it, but it was very different from the books. 'Shadowhunters' is also very different from the books, but does follow the general storyline.
2. Percy Jackson (2010, 2013)
Percy Jackson lasted two movies! But still the differences from the novels weren't accepted by fans and the movies kind of failed. They were enjoyable, but not what the fans wanted.
3. Beautiful Creatures (2013)
I enjoyed 'Beautiful Creatures' when I first saw the movie, but then I read the book. Honestly they messed this up so bad. The casting was perfect, honestly, but they changed they story so badly that it just couldn't be fixed. Even though the other books really had potential.
4. The 5th Wave (2016)
Same goes for this one. I really liked it, but the general public didn't seem to. I haven't read the book yet, so I can't Judge on the differences. The others aren't being made into film, that's for sure.
5. Divergent (2014, 2015, 2016)
This is quite a sad story. Divergent was made into a movie, same goes for Insurgent and the first half of Allegiant. But because Allegiant did so bad at the box office, the second part of Allegiant, titled Acsendant was brutally cancelled. The last words haven't been said about this, at least that's what they're telling us, because I think they are tho.
