If Felicity wasn’t on Arrow it would be a total turd, she’s really the best part about Arrow by making the show less dark and gloomy all the time.
If she wasn’t around who would be the heart of the show fucking Laurel? NO! How about Thea? still nope, because she’s too much like her brother.
You’re probably the only one or part of very few who liked the flashbacks, even season one flashbacks were too often. I get we need it for origin story but they drug it out way too long for me personally.
Just devote an episode maybe two max for the island stuff I mean we are still dealing with island crap it feels like a writer crutch, “we need The Arrow to have met or dealt with the bad guys before, have it happen back on the island”
That deserted island is very popular probably even a Holiday Inn on the other side of some of those trees.
