It’s definitely PART of the issue. It’s even a bit of an issue on Doom Patrol. Difference is that the writing on Doom Patrol is strong enough to overcome iffy SFX. It was the same thing with Swamp Thing before that got canceled: great writing and acting but the effects felt lacking. And it’s not like WB can’t AFFORD to give these shows blockbuster budgets. They certainly went all out for Game of Thrones.
