Just going over 2015, did you watch:
Inherent Vice
Predestination
The Duke of Burgundy
R100
Son of a Gun
The Loft
Jupiter Ascending
Kingsman (which is a really James Bond riff)
Focus
Chappie
Danny Collins
The Gunman
Spring
Serena
Woman in Gold
Lost River
Age of Adaline
That's just up until May 2015 and I skipped a bunch of films.
Hollywood does make original movies, people don't watch them. They make sequels and reboots because that's what people watch. If you didn't watch any of those films above, you're part of the problem. Did you watch Bridge of Spies by Steven Spielberg? No? Burnt, Our Brand is Crisis, The Last Witch Hunter, and Scouts Guide to the Zombie Apocalypse? Those are original films that just came out and probably aren't on your radar. You know what you probably will see? Spectre 007.
The "next Se7en or Usual Suspects" doesn't just pop freaking fully-formed from a studio, all perfect and wonderful. Filmmaking is hard. No one knows what's going to be good, and yet they try. Hollywood makes original films (that you don't watch). Excuse them if their big budgets go to what they believe to be less risky projects.
