I disagree with you that it's horrible. After re-watching season 3 on Netflix I can for sure say watching it at your own pace is the best method. Not saying it's a great season but it's better then I thought. And season 4 both episodes have been solid imo.
Season 3 was HORRIBLE. Rushed out exit of Roy Harper, a stupid reason for why Oliver didn't die by Ra's, the horrible Felicity/Ray stuff, the horrible Felicity/Oliver stuff, the huge letdown of who killed Sara, the horrible story of Lance vs Arrow going on and on and on, and the bad handling of Ra's. Not good.
Season 4 has been equally, if not more bad. Oliver and Felicity BS, Oliver running for major, and a BAD version of one of my favorite characters, Anarky.
Now, there is some good stuff and I focus on the good, but it's 99% shit. I'm only watching it for Constantine.
