Maze Runner - worth a watch but got the impression that its going to go all hunger games and start churning out sequels every christmas for the next 3 years.
This is the aim.
It all started with Twilight, which made big money. So Hollywood is now searching out stories, written by women, which are about teenagers.
Twilight
The Host << this was the big hope and seemed to fail
Hunger Games << using the pulling power of J.Lawrence this is doing well.
Divergent << an shocking amount of money was spent on advertising this movie and it did reasonably well. Sequel has completed filming.
Maze Runner << sequel has started filming
All these movies appear to be made in the same style/formula, camera angles, hue, etc. Almost as if the same producers/directors/set designers are making these movies. All these movies seem to be timeless and set in a parallel universe - ie. not in the past, not in the future.
There will be more, of that we can be assured.
If you enjoy these movies starring teenagers, you may want to check The 100. Once again, the cast is almost entirely made of teenagers. The style is different, though.
The other genre which is a proven money maker is the comic book movie.
And the 3rd (almost guaranteed money-maker), the animated movie - Frozen made a huge amount of cash a year ago.
