Thea is an odd example, she has a BF, she still has her club and she's simultaneously handling Oliver's campaign. She has plenty to do.
We never see the club. Her "boyfriend" and Oliver's campaign literally exist in one place, by the lair. The characters have had their lives truncated and condensed into things that only occasionally serve the plot. They stopped being people.
It gives them more time to spread over the remaining characters though. It is the same reason Malcolm needs to go.
You really think that's going to happen in a post-Olciity world? Where do you think all that time went in the first place? It's certainly not being taken up by the 5 or so seconds it takes for Laurel to do her canary cry pose. Most of these characters have been around since season 1 but all of a sudden
they're the problem? They lost their identities and that started back around season 3. I remember feeling like Roy was on a trajectory in seasons 1 and 2. He
used to be a douche! When he put on the suit, he ceased being anything. He was just there. he was so forgettable that he got blasted by Ray's energy blast and was left a crumpled mass in a damp Vancouver lot.
Well..for one superhero part of the show will improve, because at this point they've turned Oliver into pathetic chump, just to make other character feel less useless. And this is superhero show. Superheroics at the core of it.
Plus does anyone really care about Laurel's private life?
Ollie gets nerfed when the story calls for it, just like Barry. As much as people loved The Climb, the reason Ollie lost was because he looked like a child fighting an adult. Peak Mirakuru slayer Ollie would have had a completely different fight, and that has nothing to do with making his friends look good.
Basically I want the writing to improve. It was never great but it took a nosedive in season 3 and started to recover a bit. Sounds like other people want them to cut elements and pray that the writing somehow comes together because of it.
