Yeah, I had a sinking feeling about the tone of the season from the opening credits, both based on the lyrics and the imagery.
As annoying as the release schedule is (especially with the World of Remnant docs interspersed with the actual episodes and the delay if you're not an RT subscriber) at least the episodes have consistently been in the 10-15 minute range this season. There were several episodes in season 1 where the opening and closing credits were longer than the actual content.
I understand them being a lot more somber with Monty Oum's passing and I know they're supposed to working from his notes. I just originally started watching it as mildly-silly high-action escapism, so the darker turn wasn't really what I was looking for.
I'm still not sure what the bad guys' agenda is. Seems like everyone getting eaten by monsters would be bad for them, too.
