SUPERHERO
Ryan Reynolds is the Green Lantern
There has been an extraordinary amount of superhero movies released in the past 5 years. There have been 19 superhero movies produced in the last 5 years. One could argue that special effects give these films a reason to be made now. I agree but I feel that production companies fear taking a risk on an original screenplay. They would rather go with what has been proven hence the next category.
THE UNDEAD
Colin Farrel as a Vampire in FRIGHT NIGHT
Zombies and Vampires have stormed Hollywood. It seems like every year more and more vampire/zombie movies are being produced. From Twilight to Zombieland to Priest to 28 Weeks Later to I am Legend the movies about the undead were being produced in droves for decades but are only now in the major sphere.
SEQUELS AND REMAKES
To bolster my point I left these for last. If one movie does well Hollywood will make part two as fast as possible no matter how good the movie is. It is unbelievable that films like Blade and the Hulk are being rebooted in less the ten years after their first release. Some remakes are acceptable but only if they do the original justice. As far as sequels go lets look at Hangover 2... an unnecessary sequel that was funny but obviously rushed.
But time and time again Hollywood is vindicated by ticket sales. Hangover 2 is #1 at the box office and it opened by making over $100 Million. Their recipe for success seems to be working but it is keeping their audiences from new original ideas. Hopefully when the economy recovers the ticket prices will go down and production companies won't be afraid to take a risk again.
