Arrow has benefited from the crossover boosts though,it wouldn't be anywhere near the others without them.
Still I dont think you can deny that the show right now doesn't hold a candle to what it was just years ago. Strictly going by ratings then the current season>season 2,would you agree with that? Olcity itself I dont think people have issue with,its that almost everything revolves around Felicity now. Thea is the only exception but she's been essentially stuck in the same storyline for 2 seasons. The fight choreography does not hold up now,I remember when people considered it the best choreography in cbms and shows,these days not only are the stunts themselves bad but the fights have lost consistency. Just as an example Darhk beats Ollie h2h,then Ollie beats him,then Darhk beats Ollie, then Ollie owns him. The less that is said about the island sequences,the better and these used to be the best aspects of the show.
The pandering has gotten completely out of hand,there's no denying it. Guggenheim actually created a legit sequence involving Felicity's plant that was destroyed in S3 being inserted in to the Lazarus Pit and coming back to life. Let that thought sink in,he actually blew a portion of the budget,it was a proper sequence with music. Arrow is supposed to be gritty crime drama not Felicity Smoak's fantasies, if they want they can make a romance show starring Amell and EBR, many of the obsessive fans cant even tell the difference between the actors and the characters

for me as long as they're gonna bring additional Batman/DC characters I will always be interested in giving the show a shot which is why I'm still watching. These days I'm hoping WB imposes a proper embargo on all Bat related characters and most DC characters. Also you're wrong about Laurel being killed because of some high decree,these people outright stated that they didn't know who they killed all those months ago.
