When did they get it right for Crystal S1/2? Outside of maybe of very select scenes. They didn’t have one episode that was completely on model.
But no, you're right. It was mostly just select scenes rather than entire episodes. I know people praise ep 1 and 5, as they should compared to the rest, but even those are all over the place.
However, there were a few scenes in s1-2 I thought were well done. You could really tell when someone was given the time and budget to polish a scene. My issue is these were mostly the still shots and as soon as things start moving...woah!
I prefer the 90s style, but I was still disappointed when the defaulted back to something similar after Crystal 1-3 was received poorly. I was enjoying the new styles, I just wanted more polish.
