Oh, I agree there's legit criticisms. Lots of them. The problem is wading through all of the crap to get it. This is especially true of hugely popular stuff like Star Wars, GoT, etc. Some fans might have thought The Americans finale was underwhelming, but it's not slamming up messageboards anywhere.
Basically what im saying is criticism is valid, but there's zero point to trying to spend hours online on forums like this trying to get it. At least if you're actually the creators themselves. Think about how many hours of "no talent shit-stains" you'd have to parse to get to one reasonably well thought out point, renumerated enough times across even more "you ruined everything, fuck-tards" to even begin to register. It's a waste of their time.
