If you don't like what's out there...

If you don't like the news: go make your own. A phrase known by many, but not enough people take it seriously. The papers are only reporting war and crime? Do something that helps make peace. You're tired of reading about poverty? Then donate to charity and help those in need. If you don't like the creative content out there: make your own. Comics don't make you laugh? Make your own and spread your kind of humor to make yourself and others smile. If you don't find literature that suits you, someone else is probably looking for it too.
Complaining is the most easy, because that means you don't have to do anything to improve yourself or the world around you. It's easy to complain about what others do, what they make and poke holes in what they believe in, but until you've tried to change the world around you, you will have no idea what it's like. Critiquing is easy, but handling critisism is a lot harder. If you want something to change, maybe you should stop sitting around and complaining about it, and actually try to contribute to the change you wish for.
Change doesn't happen just because you want it to, and it doesn't happen overnight. Change takes time and dedication, and until you're ready to show your passion about a subject and you're willing to make a concious effort to improve the world around you, I don't see how you could possibly have the right to complain.
