I feel like this season of Invincible has been filler... Don't get me wrong, the show is awesome, but it just feels like the plot hasn't advanced at all this season
The animation quality dip this season has been especially noticeable, hell they have a couple scenes where it's static talking for several minutes (looking at you pancake scene) and nobody's moving. It's been that way since the beginning, but it's getting really old after seeing what shows like X-Men 97 can pull off.
