I don’t watch GoT, in fact I think it’s the most overrated TV show ever (sue me :p), but these petitions are so idiotic. People these days are way too entitled. So your beloved TV show turned sour, boo hoo, cry me a river. Its happened before (e.g Dexter) and it will happen again.
Same thing with the masses petitioning against Robert Pattinson playing Batman. Seriously, people need to get over themselves. The poor dude. Imagine how excited he must have been to be cast and then imagine how he must feel seeing all these petitions against him.
