LOL!!!
The funny thing is, a lot of 'casual' fans DO believe Gattis is one of the best writers. My assumption is that it's mainly because of his relative fame and visibility compared to the other writers and the affection he's accumulated from that.
He is a terrible writer and I honestly say that with no malice. I always think he seems like a nice guy to know: interesting, passionate about what he does, knowledgeable, personable... I like him and would like him to be a good writer... but he isn't. At this point I just accept it. He'll be there come what may. He may even be the next showrunner, who knows. Just go into his episodes with low expectations.
