Ok, so my dad has worked in tv for 25 years, I know how the industry works. You can complain about Heros of Cosplay all you want, in all likelihood, SyFy WILL. NOT. CARE. Seriously. Unless you're a huge influential cosplayer that they might want on the show, a media presence, or anyone that has a large mainstream audience really, your complaints don't matter to them. If you really hate this show and want to do something about it, the only way to make them notice is to not watch it. Do not give them viewership. Show them that you refuse to support this show. If people watch the show, no matter how much we complain, nothing will change. However, if their ratings suck and their viewership is terrible, then either they care enough to look into why and fix it, or the show gets axed. Either one is a victory at this point. Don't watch. Not for curiosity, not just for the costumes, not for anything. If you have to, find a stream that won't add to their viewership.

Just stop watching. That's the only way to make them care.
