I feel like a lot of grief people have with S2 of Wednesday (and honestly, all current shows but especially further seasons) is linked to the 8-episodes format.
Like obviously, the first seasons are often introductory and try to not put too much, or can get away with not developing everything they set up from the get go because it's a first season. They ease you into their universe and set things up. So 8 episodes can work.
But then, they have to develop on the elements that weren't resolved in S1. And they need to introduce new elements to keep the story going and interesting and not just act as a conclusion to S1 (after all, you need to set up the upcoming seasons).
And then, 8 episodes isn't enough anymore. You can't develop old characters properly, introduce new characters with enough in-depth informations, you can't take your plots as far as you'd have hoped, etc.
Not to fully excuse the writers, but i think we really need to remember the context. 8 episodes seasons are new, and we had longer seasons for a reason. Heck even just going back to 10 episodes like for GoT would allow for 2 more hours to dig more on some character development or make some plots longer.
